narrow: drop unnecessary overrides of patch
The patch overrides became unnecessary when I made context.status()
filter by the narrowspec in
e411774a2e0f (narrow: move
status-filtering to core and to ctx, 2018-08-02).

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).
