alsaLib: add upstream pcm interval patch to fix audio #53552
fixes audio for Audacious, Old School Runescape (yet to be packaged, but I'm working on that!),
Cleaned up the commit message and pushed to staging as of 40ce44f, since I have tested this package for the past few weeks and ofborg found no issues, and because I don't see any maintainers to ping. Furthermore, other linux distributions have had this patch included in their alsa-lib packages for enough time that any serious regressions would have been reported
Nonetheless, please feel free to ping me about any issues that might arise and I'd be happy to help fix it, or revert.
