Leo Yan 735a3ac370 perf test probe_vfs_getname: Add regex for searching probe line 
Since commit 611851010c ("fs: dedup handling of struct filename
init and refcounts bumps"), the kernel has been refactored to use a new
inline function initname(), moving name initialization into it.

As a result, the perf probe test can no longer find the source line that
matches the defined regular expressions. This causes the script to fail
when attempting to add probes.

Add a regular expression to search for the call site of initname(). This
provides a valid source line number for adding the probe. Keeps the
older regular expressions for passing test on older kernels.

Fixes: 611851010c ("fs: dedup handling of struct filename init and refcounts bumps")
