match: don't util.normpath() cwd

The problem here is that `util.normpath()` calls `util.pconvert()`, which
switches to Unix style separators.  That results in two test failures like this
since 5685ce2ea3bf:

    ERROR: test-globalopts.t output changed

Martin originally had `os.path.normpath()` (which *would* work here too), but
changed it during review.  He didn't remember why he thought any form is needed
here.  Most uses simply pass '' or `repo.getcwd()`, so these should generally be
in local format anyway.  It seems better if `cwd` and `root` use consistent
styles here.
