Add support for /etc/rc.local.d directory, ala SYSV. If the purists

don't like it, they don't have to use it.  The check makes sure that
/etc/rc.local.d exists before attempting to do anything with it.  Now
packages will be able to add their startups as /etc/rc.local.d/<pkgname>.sh
in order to get local startup behavior.  Maybe we can stop adding
knobs to /etc/sysconfig for ports/packages now?
