I believe the correct method is just to change the buildreq to systemd-boot-
unsigned for everything, and add a note to redhat/rebase-notes.txt to revert
that new MR for stable fedora until F37 is EOL. os-build does not build
kernels for anything other than rawhide, and when I do branch for stable
Fedora, that branch will not build kernels for ELN/RHEL, so the current
behavior is correct.
