[aur-requests] [PRQ#15391] Merge Request for mutter-781835-workaround

Terence [1] filed a request to merge mutter-781835-workaround [2] into mutter-performance [3]: The old name isn't relevant anymore. The workaround in itself has been replaced with a proper fix and the package purpose was extended.
