Subject: keymap/consolefont: source rc.conf properly from $BASEDIR

This is partially in response to FS#24685, which should hopefully cut
back on configuration duplication on non-sysvinit systems. This does,
however, also fix a bug with keymap/consolefont pulling the wrong
rc.conf when BASEDIR is not '/' or unset.
