[BOLT] Fix pacret-synchronous-unwind.cpp test (#171395)

Browse Source 
The test case build a binary from C++, and checks for the number of
functions the PointerAuthCFIFixup pass runs on.
This can change based on the platform. To account for this, the patch
changes the number to a regex.

The test failed when running on RHEL 9.
