[PATCH v10 11/12] Add some reftable testing infrastructure

["Han-Wen Nienhuys via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Han-Wen Nienhuys <hanwen@xxxxxxxxxx>

* Add GIT_TEST_REFTABLE environment var to control default ref storage

* Add test_prerequisite REFTABLE. Skip t/t3210-pack-refs.sh for REFTABLE.
