trivial: provide a fwupdate transition for RHEL 8
trivial: provide a fwupdate transition for RHEL 8

This is similar to commit 1ff11646305 ("trivial: debian/control*: Update
for fwupdate transition") but to provide a fwupdate transition in RHEL 8
where the fwupdate{,efi} packages are still present.

There is no need to do this for Fedora, since the fwupdate packages have
already been retired.
