dracut-systemd/rootfs-generator.sh: always create generated files.

When 'systemctl daemon-reload' is run, systemd will clean out
/run/systemd/generator and re-run all the generators.
So it is important that the generators always create the required
files.

rootfs-generator.sh currently does *not* create the desired files
if $hookdir/initqueue/finished/devexists-${_name}.sh
exists.

This is not removed by "systectl daemon-reload" so the first time this
generator is run it will do the right thing.  Subsequent times it
won't.

This results in incorrect timeouts after "daemon-reload" is run.

So let the existence of each file only guard the creation that file.
