Setup translation for security-guide-rst

Follow setup of openstack-manuals for translation of RST files:
* Add generatepot-rst tox environment (called by infra scripts)
* Enable translation in doc-tools-check-languages.conf
* Add file security-guide-rst/source/locale/security-guide-rst.pot
  (empty for now, the infra scripts will import the realy content)
