What patch did you apply? For this sort of thing, I could be convinced
to bump the mozjs release with said patch included.

Correct. This is one of the reasons we try to push for folks to upstream
their work. Otherwise you get a snowball of things you have to maintain
yourself that just keeps growing.

This is likely because yum checks that the packages are properly GPG
signed on install. Since your package isn't signed with the distro key
it may not behave as you'd expect.

You should be able to create the metadata from any centos install,
however cross-compiling it would probably break things.

Which packages? KVM support is already built into the distro, so are
these additional, or patched versions?
