fix(dracut-systemd): run systemctl daemon-reload after remove_hostonly_files

Dependencies to systemd .device unit files are marked as "hostonly" in the
special file hostonly-files. These .device unit files can be removed using the
`rd.hostonly=0` command line parameter. But, since systemd v252
(https://github.com/systemd/systemd/pull/24054), the initrd-parse-etc.service
service does not run `systemctl daemon-reload`, so systemd keeps waiting
for these .device units to show up.
This means that if a hostonly device is not available for any reason at boot
time, using `rd.hostonly=0` has no effect and the system will not boot.
