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.

+	  The 2.4 kernel changed the kernel start address from 0x310000
+	  to 0x810000 to make room for the Wildfire's larger SRM console.
+	  Recent consoles on Titan and Marvel machines also require the

+	  If you're using aboot 0.7 or later, the bootloader will examine the
+	  ELF headers to determine where to transfer control. Unfortunately,
+	  most older bootloaders -- APB or MILO -- hardcoded the kernel start
+	  address rather than examining the ELF headers, and the result is a
+	  hard lockup.
+
+	  Say Y if you have a broken bootloader.  Say N if you do not, or if
+	  you wish to run on Wildfire, Titan, or Marvel.
