Add a mechanism to include files added by ports which contain

the names of directories to include in the base ldconfig script.
This will eliminate the need for each port to install its own
boot script which does nothing but ldocnfig a given directory.

This code was developed by flz (ports committer), discussed on
freebsd-rc@, and modified slightly by me.
