Log Message:
RCD_SCRIPTS_EXAMPLEDIR is no longer customizable.
And always is defined as share/examples/rc.d
which was the default before.

This rc.d scripts are not automatically added to PLISTs now also.
So add to each corresponding PLIST as required.

This was discussed on tech-pkg in late January and late April.

Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere
and remove the RCD_SCRIPTS_EXAMPLEDIR itself.
