perf tests trace+probe_vfs_getname.sh: Accept quotes surrounding the filename

With augmented_raw_syscalls transformed into a BPF skel made the output have a "
around the filenames, which is not what the old perf probe vfs_getname
method of obtaining filenames did, so accept the augmented way, with the
quotes.

At this point probably removing all the logic for the vfs_getname method
is in order, will do it at some point.

For now lets accept with/without quotes and make that test pass.
