Subject: scripts/get_maintainer.pl: Add -f directory use

Don't require a specific file in a directory to be tested.

Also Arnd Bergmann pointed out that the MAINTAINERS pattern requirement
that directory patterns have a trailing slash was unnecessary and was
likely to be error prone.  Removed that requirement.
