Predicate CTF support on MK_CDDL rather than MK_CTF. The latter just
determines whether programs/libs are built with CTF data, whereas the
former determines whether libctf is built, which is what we care about.
libproc shlib version has been bumped, so add the previous version to
the obsolete file list.
