Enable fedora-readonly.service and fedora-import-state.service
fedora-readonly.service is a oneshot service that runs during bootup
and configures read-only root. It used to be permanently enabled using
a symlink in /usr/lib/systemd/system, and moving it to presets is a
step to allowing it to be disabled.
fedora-import-state.service is a oneshot service that runs after the
switch to the real filesystem and and moves some state from /run to
/etc. It shouldn't be used anymore, and programs should instead check
/run for their configuration. networking and some fcoe-related stuff
used in dracut still uses that, so until that is fixed in those
projects, we need this enabled.
