tests: do not rely on external "patch"
Some of our tests assumed a working "patch" command to produce expected results when checking "git-apply", but some systems have broken "patch". We can compare our output with expected output that is precomputed instead to sidestep this issue. Signed-off-by: Junio C Hamano <gitster@pobox.com>
