emulators/wine-devel: Update to Wine 6.18
This includes the following changes:
- Shell32 and WineBus libraries converted to PE.
- Unicode data updated to Unicode version 14.
- More work towards Dwarf 3/4 debug support.
- HID joystick enabled by default.
- Various bug fixes.
files/patch-amd64-vs-x86-64, which I submitted upstream, is obsolete
now and the issue has been addressed upstream even more thoroughly,
so drop our local patch.
