manifest: Exclude unneeded udisks2

[travier]

With RHEL 8.4, fwupd got pulled in as provider of dbxtool and that also
included udisks2 as a recommends. But udisks2 is apparently only needed
for encrypted swap checks in fwupd and is not even included in FCOS, so
manually exclude it.

For BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1953105

@hughsie Could you confirm that udisks2 is not strictly required for firmware updates in fwupd? Thanks!

udisks2 is not strictly required for firmware updates in fwupd

We indeed use it to find the ESP partition, but admins can hardcode this in /etc/fwupd/uefi_capsule.conf instead if required. If you're not using any plugins that use the ESP then you don't need udisks. I guess that depends on if you're ever likely to see a capsule update in reality on openshift.

Regarding the ESP: coreos/fedora-coreos-config#794

Ultimately we may need a shared userspace component for dealing with the ESP, which may be bootupd. Not sure.
