manifests/group: fix ID for "input" group

This fixes the static GID for the `input` group, properly using the
Fedora-wide reserved ID `104`.
This group is mostly used as the owner of ephemeral entries under
`/dev`, thus it should be safe to update (upon booting into the new
deployment, devices will get created from scratch with the new GID).
