Fix scriptlets for various services and remote-cryptsetup.target
    
    ... (rhbz#2217997)
    
    systemd-homed.service and systemd-portabled.service are in
    systemd-udev but the scriptlet was attached to main subpackage, so it
    wouldn't work because the unit file wasn't installed yet when it was
    invoked. systemd-pstore.service and remote-cryptsetup.target were
    forgotten, so they wouldn't get enabled on installation.
