match: combine regex code for path: and relpath:

The regexes for path: and relpath: patterns are the same (since the
paths have already been normalized at the point we create the
regexes).

I don't think the "if pat == '.'" will have any effect relpath:
because relpath: patterns will have the root directory already
normalized to '' by pathutil.canonpath() (unlike path:, for which the
root gets normalized to '.' by util.normpath()).
