dev-manual, ref-manual: Added notes for Systemd-based images.

Fixes [YOCTO #5159]

In the dev-manual, I located instances where a note about using
VIRTURAL-RUNTIME_initscripts = "" in the local.conf file would
be appropriate.  Three areas updated.

In the ref-manual, I located the note in the systemd.bbclass
section and the variable descriptions for SYSTEM_AUTO_ENABLE,
SYSTEM_PACKAGES, and SYSTEMD_SERVICE.
