[PATCH] faudio: Update to 21.12-3-gbbc9519.

[Rémi Bernon]

This will be in next FAudio release. The PCM format change is required
to fix a regression in some games, such as Far Cry 4, where audio
doesn't work anymore since the move to FAudio Win32 platform.

Signed-off-by: Rémi Bernon

I believe FAudio uses monthly releases, which may be late for Wine 7.0,
depending on our release schedule. We can also wait for FAudio 22.01
otherwise.
