greenwave: handle ELN product_version rename, enable RemoteRule

See https://github.com/fedora-infra/bodhi/pull/6110 . We want to
be able to gate (only) Fedora ELN kernel updates via gating.yaml
(RemoteRule). However, if we just turned on the RemoteRule policy
for "fedora-eln", suddenly hundreds of existing gating.yamls which
specify "fedora-*" would apply to ELN, which we don't want.

To solve this, we will make Bodhi use "eln" not "fedora-eln" as
the product_version for ELN. That requires us to add "eln" to the
null policies. Let's also enable RemoteRule for "eln" at the same
time. This should not cause any existing policies to apply (unless
there are any which just specify '*', I guess) but will allow us
to add a kernel policy that applies to 'eln'.
