Subject: install MOH files under datadir
Author: Tzafrir Cohen <tzafrir.cohen@xorcom.com>
Bug: https://issues.asterisk.org/view.php?id=16906

If a relative path is used in the datadir, make it use the datadir (normally
/usr/share/asterisk on Debian packages) rather than the var_dir (normally
/var/lib/asterisk).

Issue is currently in review by upstream.
