[PULL 12/13] configure: correctly honour --disable-containers

["Daniel P. Berrangé" <berrange@redhat.com>]

The configure script originally only probed for 'runc' command
in order to handle cross-compilation containers. The Makefile
under tests/docker would then probe again when used.

In order to eliminate the additional probeing, we changed
configure in commit c4ce04cfb7460d46c0262d437a7f35bb5c5fc449
to always probe for 'runc', so the result could be passed
along to tests/docker make rules.

That commit overlooked that the 'probe_target_compiler' func
was relying on '$runc' == 'no' as a proxy for the state of
the --disable-containers arg.

When we started unconditionally probing, that short cut no
longer works and we must explicitly check "$use_containers"
too.
