Update to Wine 2.21. This includes the following changes:

• Still more metafile support in GdiPlus.
• Indirect draws support in Direct 3D.
• Services fixes on WoW64.
• Better DPI scaling in the Shell Explorer.
• Various bug fixes.

On the way, generally disable PulseAudio support, not just for the
Wine Staging case (where this originally only existed). [1]

Talking about Wine Staging, mark that (via the STAGING option, and hence
the wine-staging port as well) as BROKEN once again; that patchset still
is not available yet, and we cannot wait forever.
