change local to run programs

This changes the local service so that it will run programs located in
@sysconfdir@/local.d instead of the local_start and local_stop functions
from @sysconfdir@/conf.d/local.

The advantage for the user is that these programs are not part
of the openrc package, so the user does not have to worry about them
being overwritten when openrc is upgraded.
