            Disable -devel-engine on RHEL 10+

ENGINE is deprecated but the header is still (separately) available for
Fedora.  While still built for binary compatibility, the header has been
completely removed from RHEL 10 and later, and anything in EPEL 10 has been
ported to work without it.  All the necessary changes have also been
brought back to ELN and ELN Extras.
