emulators/wine-devel: Relinquish maintainership

After working on our Wine ports for more than 21 years, maintaining
for more than 19 years, time has come to hand over the baton. Sadly
despite multiple requests to committers as well as some non-committers
nobody stepped up yet, so return to the pool.

Still happy to provide guidance and help on working with upstream or
operating the (crucial) nightly testers I have been running.
