Add kwin scratch build to fix RHBZ #2047503 as an F36 workaround

Scratch build because we don't have a single-build update with
the fix, it's likely gonna be included in the 5.24.2 megaupdate.
I don't want to use that whole thing as a workaround, so I did
a 5.24.1 scratch build with the fix instead.
