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/block/rnbd<N>/rnbd/unmap_device
+Date:		Feb 2020
+KernelVersion:	5.7
+Contact:	Jack Wang <jinpu.wang@cloud.ionos.com> Danil Kipnis <danil.kipnis@cloud.ionos.com>
+Description:	To unmap a volume, "normal" or "force" has to be written to:
+		/sys/block/rnbd<N>/rnbd/unmap_device
+
+		When "normal" is used, the operation will fail with EBUSY if any process
+		is using the device.  When "force" is used, the device is also unmapped
+		when device is in use.  All I/Os that are in progress will fail.
+
+		Example::
+
+		  # echo "normal" > /sys/block/rnbd0/rnbd/unmap_device

+KernelVersion:	5.7
+Contact:	Jack Wang <jinpu.wang@cloud.ionos.com> Danil Kipnis <danil.kipnis@cloud.ionos.com>
+Description:	The file contains the current state of the block device. The state file
+		returns "open" when the device is successfully mapped from the server
+		and accepting I/O requests. When the connection to the server gets
+		disconnected in case of an error (e.g. link failure), the state file
+		returns "closed" and all I/O requests submitted to it will fail with -EIO.

+Description:	RNBD uses RTRS session to transport the data between client and
+		server.  The entry "session" contains the name of the session, that
+		was used to establish the RTRS session.  It's the same name that
+		was passed as server parameter to the map_device entry.
