[PATCH] gdb/testsuite: fix gdb.python/py-framefilter-invalidarg.exp with clang

[Guinevere Larsen]

The final test of gdb.python/py-framefilter-invalidarg.exp expected that
the the backtrace only printed the source file name. However, when using
clang, gdb will always print the full path to the file, which would
cause the test to fail. This commit introduces a regexp that optionally
matches paths, preprended to the file name, which fixes the clang
failure without introducing gcc failures.
