common: Remove ostree-grub2

New systems are setup with a static GRUB config and thus don't need
support to generate the GRUB config dynamically.

Older systems will be migrated to a static GRUB config during their
first boot on Fedora 42.

See: https://gitlab.com/fedora/ostree/sig/-/issues/35
Fixes: https://github.com/fedora-silverblue/issue-tracker/issues/120
