pick-ui: stop backporting every revert
Wee had a few bugs introduced in the release branches because of a commit fixing something followed by a revert of an older commit, and only the revert made it to the release branch, breaking things.
Let's stop backporting every revert, and make it mandatory for revert
commits to contain a cc: mesa-stable
of fixes:
if they need to be
backported like any other commit.
