pre-push gate: clear git's hook environment (GIT_DIR and friends) so the self-tests' nested git never acts on this repository

Browse source 
The first master push through the gate died inside remote-run.sh's self-test: its mirror push ran this repository's hook against the fixture tree. Shown fixed by a push to a local bare repository (the real hook, GREEN).
