t/Makefile: stop setting GIT_CONFIG

Once upon a time, the setting of GIT_CONFIG in the environment could affect how tests ran. Commit 9c3796f (Fix setting config variables with an alternative GIT_CONFIG, 2006-06-20) unconditionally set GIT_CONFIG in the Makefile when running tests to give us a known starting point. This is insufficient for running the tests outside of the Makefile, however, and 8565d2d (Make tests independent of global config files, 2007-02-15) later set GIT_CONFIG directly in test-lib.sh. At that point the Makefile setting was redundant, but we never removed it. Let's do so now. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
