The RequiresMountsFor configuration option of systemd.unit (added in
systemd version 201) not only adds the Requires and After options for
the required mount unit, but it adds them for all mount units required
to access the specified path.
So this change is both a simplification, and an improvement.
Not only will all needed mount units be added to Requires and After, but
the overlay path does not have to be a mountpoint, but can be at any
directory level beneath a mountpoint.

OverlayFS systemd helper unit might require more pre-processing
commands. It gets more complicated to embed them in a unit file, because
systemd shell subset is limited and might require additional escaping.
Move the command to a separate script, thus simplifying systemd unit.

Split ExecStart into two commands because systemd interpret an ExecStart
entry as a single executable with multiple parameters.
systemd[1]: Starting Overlayfs directories setup...
mkdir: cannot create directory '&&': Read-only file system
mkdir: cannot create directory 'mkdir': Read-only file system
