Andy McCrae eee919ad21 Fix lxc_net configuration for CentOS/SUSE
For CentOS/Red Hat and SUSE the network post-up/post-down scripts are
configured after the bridge has been brought up, and the handlers have
been flushed.

We need to configure the post-up and post-down scripts before the
restart bridge handler is flushed, so that dnsmasq is configured and
running before we attempt to install packages into the container.
