Add deltifier test.
This test kicks in only if you built test-delta executable, and makes sure that the basic delta routine is working properly even on empty files. This commit is to make sure we have a test to catch the breakage. The delitifier code is still broken, which will be fixed with the next commit. Signed-off-by: Junio C Hamano <junkio@cox.net>
