log: fix handling of root (or empty) path provided by matcher (issue6478)

Since 27d6956d386b "match: use '' instead of '.' for root directory",
'.' should be translated to ''. We can't blame repo.file() about this because
an empty string is invalid as a file path, but I found at least two callers
(_makematcher() and revset.filelog()) would crash because of this path[0].

So let's make repo.file() accept an empty string. path[0] == b'/' wouldn't
work on Python 3 anyways.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
