Commit 8cbfbe487a (package/skeleton-systemd: systemd-ify mounting /var
tmpfs with ro rootfs) removed the fstab handling of /var, and left the
macro deal solely about keeping / read-only.
However, the code about how the var factory is handled was left above
the macro, which is now misleading and confusing.
Move the comment closer to the actual rootfs-pre-cmd hook which actually
deals with handling the var factory.
