Restore SMF support in the build system

libscf detection (AC_CHECK_LIB(scf, smf_enable_instance)) was lost
in the automake rewrite (978c7b2e89aa) and was not added back when
the build system was replaced with meson, so HAVE_LIBSCF was never
defined and the Solaris SMF code in bin/named was dead code.

Detect libscf on SunOS hosts and link named against it.
