Subject: [PATCH] Fix bug in testing mock

If nonexistent files appear in the keyring list, grep will return an error
even if a later keyring contains a match; this will cause the mock tool to
incorrectly report not finding a key.  This bug was hidden by the main
gatekeeper only using one keyring on each gpgv run.
