emulators/wine: Add dependency on alsa-plugins

When using the ALSA option (which is not the default) audio did not
worke - no audio device appeared for playing and recording and the
following message appeared:

ALSA lib dlmisc.c:285:(snd_dlobj_cache_get0) Cannot open shared
library /usr/local/lib/alsa-lib/libasound_module_pcm_oss.so

Providing alsa-plugins at run time addresses this.

Bump PORTREVSION accordingly.
