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.

+Description:
+		This folder includes the attributes related with PPI (Physical
+		Presence Interface). Only if TPM is supported by BIOS, this
+		folder makes sense. The folder path can be got by command
+		'find /sys/ -name 'pcrs''. For the detail information of PPI,
+		please refer to the PPI specification from
+
+		http://www.trustedcomputinggroup.org/
+
+		In Linux 4.2 ppi was moved to the character device directory.
+		A symlink from tpmX/device/ppi to tpmX/ppi to provide backwards
+		compatibility.
