[PATCH] selftests/ftrace: allow relative paths in eprobe test

[Martin Kaiser <martin@kaiser.cx>]

The add/remove eprobe test installs an eprobe for the openat syscall,
runs ls and checks the filenames that were opened.

Commit 206b25c09080 ("tracing: eprobe: read the complete FILTER_PTR_STRING
pointer") fixed access to some string fields in eprobes. This allows for
dereferencing more filenames. In some cases, the log now shows a file
with a relative path instead of "(fault)". A relative path makes the
test fail.

Relax the filename checks to fix the test. Allow shared libraries and
locale configs that use a relative path.
