uki: get rid of RHEL-only walinuxagentcvm module in the initramfs

JIRA: https://issues.redhat.com/browse/RHEL-83003
Upstream Status: RHEL-only

The module was used for early Confidential OS disk encryption
implementation in Azure before it gained support for systemd-style root
volume key sealing. All Azure regions were migrated so the rules are now
useless.
