checkpatchCommit(): fix log format violation

By design linter is run from the directory where the repo
containing commit is located. And in case when
there is no '--show-types' option passed the resulting log
violates expected format and parseCheckpatchLog() doesn't see
what it should. Forcing the option fixes the problem.
