test-lib: remove check_var_migration

Remove the check_var_migration() migration helper. This was added back in [1], [2] and [3] to warn users to migrate from e.g. the "GIT_FSMONITOR_TEST" name to "GIT_TEST_FSMONITOR". I daresay that having been warning about this since late 2018 (or v2.20.0) was sufficient time to give everyone interested a heads-up about moving to the new names. I don't see the need for going through the "do this later" codepath anticipated in [1], let's just remove this instead. 1. 4cb54d0aa8e (fsmonitor: update GIT_TEST_FSMONITOR support, 2018-09-18) 2. 1f357b045b5 (read-cache: update TEST_GIT_INDEX_VERSION support, 2018-09-18) 3. 5765d97b71d (preload-index: update GIT_FORCE_PRELOAD_TEST support, 2018-09-18) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
