The SHA-1 key is no longer supported in RHEL 9.0. This isn't a problem
for RHEL 8.x in general, but it prevents cross building RHEL 8.x images
on RHEL 9.0, since the host (RHEL 9.0) rpm and openssl cannot import the
older keys and we fail to bootstrap the build root for the new image if
the source repositories use SHA-1 keys.
