radeonsi/test: allow to pass a filename as a test filter value

This allows this pattern:

   $ radeonsi-run-tests.py /tmp/foo
   ... reports that some piglit tests regressed ...
   $ radeonsi-run-tests.py -t /tmp/foo/new_baseline/sienna_cichlid-piglit-quick-fail.csv
   ... this only runs the test that regressed ...
