[JENKINS-12488] Exports TRIGGERED_BUILD_TAGS, which lists comma separated list of triggered build tags

Please let me know if you have questions. Using the BUILD_TAG format for the list of triggered builds seemed to me to be best, even though the "jenkins-" prefix seems unnecessary. Also, I'm assuming that build names should not contain a comma, but I think that assumption is also made elsewhere.
