Previously the KNOWN-FS value used in 'essential-services' would be
incomplete: it would lack all the file systems provided by services that
extend 'file-system-service-type' (/sys/fs/cgroup,
/proc/sys/fs/binfmt_misc, etc.) Consequently, upon shutdown,
'user-processes' would unmount these file systems before their
corresponding service had been stopped; when their corresponding (e.g.,
'file-system-/proc/sys/fs/binfmt_misc') was stopped, its 'umount' call
would fail.
This was harmless in practice, but this patch makes sure things work as
intended and file systems are unmounted in the right order.
