Remove unnecessary variables so that reproducing the buildbot is more approachble. BUILDBOT_CLOBBER shouldn't be used by users (it's actually only supported on the bot itself, see buildbot_function.sh). BUILDBOT_REVISION isn't relevant when you put a BUILDBOT_MONO_REPO_PATH, and vise-versa.
/s/master/main in branch names to point to the most recent upstream copy of zorg scripts.
