UBUNTU: [Config] linux-azure: CONFIG_LOOPBACK_TARGET=m (tcm_loop)

BugLink: http://bugs.launchpad.net/bugs/1791794

Enable the tcm_loop module, include it to the main modules package and
enforce CONFIG_LOOPBACK_TARGET=m in the annotations file to avoid
having it changed by mistake when updating the config options.
