selftests/ftrace: Fix unique symbol check in kprobe_non_uniq_symbol.tcgrafted

The current regex also matches symbols in modules, which makes the
test fail on s390 where name_show is present only once in the kernel,
but also multiple times in modules:

000001b1401cdc20 t name_show
000001b0c05e6c40 t name_show    [mdev]
000001b0c0495f30 t name_show    [i2c_core]

Fix this by changing the regular expression to only match the function
name.

+What: 		/sys/class/firmware/.../data
+Date:		July 2022
+KernelVersion:	5.19
+Contact:	driver-core@lists.linux.dev
+Description:	The data sysfs file is used for firmware-fallback and for
+		firmware uploads. Cat a firmware image to this sysfs file
+		after you echo 1 to the loading sysfs file. When the firmware
+		image write is complete, echo 0 to the loading sysfs file. This
+		sequence will signal the completion of the firmware write and
+		signal the lower-level driver that the firmware data is
+		available.
+
+What: 		/sys/class/firmware/.../cancel
+Date:		July 2022
+KernelVersion:	5.19
+Contact:	driver-core@lists.linux.dev
+Description:	Write-only. For firmware uploads, write a "1" to this file to
+		request that the transfer of firmware data to the lower-level
+		device be canceled. This request will be rejected (EBUSY) if
+		the update cannot be canceled (e.g. a FLASH write is in
+		progress) or (ENODEV) if there is no firmware update in progress.
+
+What: 		/sys/class/firmware/.../error
+Date:		July 2022
+KernelVersion:	5.19
+Contact:	driver-core@lists.linux.dev
+Description:	Read-only. Returns a string describing a failed firmware
+		upload. This string will be in the form of <STATUS>:<ERROR>,
+		where <STATUS> will be one of the status strings described
+		for the status sysfs file and <ERROR> will be one of the
+		following: "hw-error", "timeout", "user-abort", "device-busy",
+		"invalid-file-size", "read-write-error", "flash-wearout". The
+		error sysfs file is only meaningful when the current firmware
+		upload status is "idle". If this file is read while a firmware
+		transfer is in progress, then the read will fail with EBUSY.
+
+What: 		/sys/class/firmware/.../loading
+Date:		July 2022
+KernelVersion:	5.19
+Contact:	driver-core@lists.linux.dev
+Description:	The loading sysfs file is used for both firmware-fallback and
+		for firmware uploads. Echo 1 onto the loading file to indicate
+		you are writing a firmware file to the data sysfs node. Echo
+		-1 onto this file to abort the data write or echo 0 onto this
+		file to indicate that the write is complete. For firmware
+		uploads, the zero value also triggers the transfer of the
+		firmware data to the lower-level device driver.
+
+What: 		/sys/class/firmware/.../remaining_size
+Date:		July 2022
+KernelVersion:	5.19
+Contact:	driver-core@lists.linux.dev
+Description:	Read-only. For firmware upload, this file contains the size
+		of the firmware data that remains to be transferred to the
+		lower-level device driver. The size value is initialized to
+		the full size of the firmware image that was previously
+		written to the data sysfs file. This value is periodically
+		updated during the "transferring" phase of the firmware
+		upload.
+		Format: "%u".

+What: 		/sys/class/firmware/.../status
+Date:		July 2022
+KernelVersion:	5.19
+Contact:	driver-core@lists.linux.dev
+Description:	Read-only. Returns a string describing the current status of
+		a firmware upload. The string will be one of the following:
+		idle, "receiving", "preparing", "transferring", "programming".
+
+What: 		/sys/class/firmware/.../timeout
+Date:		July 2022
+KernelVersion:	5.19
+Contact:	driver-core@lists.linux.dev
+Description:	This file supports the timeout mechanism for firmware
+		fallback.  This file has no affect on firmware uploads. For
+		more information on timeouts please see the documentation
+		for firmware fallback.
