man: document that systemd-fstab-generator actually cares about roothash=/usrhash= on the kernel cmdline
It doesn't really care about the hash value passed (which is processed
by systemd-veritysetup-generator), but it does care about the fact that
it is set (and mounts the DM nodes /dev/mapper/usr + /dev/mapper/root in
that case).
