wine: fix faudio support
https://github.com/void-linux/void-packages/pull/28130

Description:
Fix for these two issues:
wine - configure: libFAudio 64-bit development files not found, XAudio2 won't be supported.
faudio - WARNING: Target "FAudio" requests linking to directory "/usr/lib".  Targets may link only to libraries.  CMake is dropping the item.

Currently built faudio lib is broken due to missing link to libSDL2.

I only tested on x86_64 and wine seems to build correctly.
I wasn't able to cross-compile wine for i686.
