systemd 261 can now natively detect and mount subpartitions.
Fixes#4544
This also works around an issue where udiskie will prompt for mounting
the /usr partitions on disk, when they are subpartitions. I didn't
file a bug upstream because it's really not clear to me what to blame
(udisks2? udiskie? udev?)
