Parameterize buildbot identity and GH_REPO

  Lets release workflows be reused unchanged across forks. Buildbot
  identity (user.name/user.email) now reads from vars.BUILDBOT_NAME /
  vars.BUILDBOT_EMAIL with the existing pixie-io values as fallbacks.

  GH_REPO is now propagated from the workflow to cli/cloud build
  scripts (operator/vizier already passed it), so artifact_utils.sh
  no longer relies on a fork-specific default. The default chain
  falls through GITHUB_REPOSITORY (auto-set by Actions) before the
  pixie-io/pixie literal.
