t/lib-patch-mode.sh: fix ignored exit codes

Fix code added in b319ef70a94 (Add a small patch-mode testing library, 2009-08-13) to use &&-chaining. This avoids losing both the exit code of a "git" and the "cat" processes. This fixes cases where we'd have e.g. missed memory leaks under SANITIZE=leak, this code doesn't leak now as far as I can tell, but I discovered it while looking at leaks in related code. For "verify_saved_head()" we could make use of "test_cmp_rev" with some changes, but it uses "git rev-parse --verify", and this existing test does not. I think it could safely use it, but let's avoid the while-at-it change, and narrowly fix the exit code problem.
