We're not in pkgsrc-wip anymore, so replace 'wip' with 'lang' in
paths to PLIST.*. ;)

While here, patch sunaudiodev.c to use AUDIO_GETBUFINFO (when available)
and BSD AUDIO_FLUSH on NetBSD and OpenBSD.  This could be
#ifdef AUDIO_FLUSH, but for now I am only certain about these two
platforms.

Bump PKGREVISION.
