#23 improve output for TEST_BOOL(memcmp(...)) and TEST_BOOL(strcmp(...)) tests

[Richard Hansen]

lib/util/tests/stringutils-test.c has a few tests that look like this:

TEST_BOOL(memcmp(...), false);
TEST_BOOL(strcmp(...), false);

If these tests fail, the output isn't very useful. It'd be nice if they dumped out the two memory regions/strings for evaluation.
