Introduce CONF_DIRS_NULSTR helper to define standard conf dirs

Several different systemd tools define a nulstr containing a standard
series of configuration file directories, in /etc, /run, /usr/local/lib,
/usr/lib, and (#ifdef HAVE_SPLIT_USR) /lib.  Factor that logic out into
a new helper macro, CONF_DIRS_NULSTR.
