tests: use "test_cmp", not "diff", when verifying the result
In tests, call test_cmp rather than raw diff where possible (i.e. if
the output does not go to a pipe), to allow the use of, say, 'cmp'
when the default 'diff -u' is not compatible with a vendor diff.
When that is not possible, use $DIFF, as set in GIT-BUILD-OPTIONS.
