SYN cookie test with reuseport BPF doesn't make sense for UDP sockets. We
don't run it but the test_progs test runner doesn't know about it. Mark the
test as skipped so the test_progs can report correctly how many tests were
skipped.

There is a typo in checking the "saved_tcp_fo" and instead
"saved_tcp_syncookie" is checked again. This patch fixes it
and also breaks them into separate if statements such that
the test will abort asap.

Currently, there is a lot of false positives if a single reuseport test
fails. This is because expected_results and the result map are not cleared.
Zero both after individual test runs, which fixes the mentioned false
positives.

Include the name of the mismatching result in human readable format
when reporting an error. The new output looks like the following:
unexpected result
result: [1, 0, 0, 0, 0, 0]
expected: [0, 0, 0, 0, 0, 0]
mismatch on DROP_ERR_INNER_MAP (bpf_prog_linum:153)
check_results:FAIL:382

The tests were originally written in abort-on-error style. With the switch
to test_progs we can no longer do that. So at the risk of not cleaning up
some resource on failure, we now return to the caller on error.
That said, failure inside one test should not affect others because we run
setup/cleanup before/after every test.

Do a pure move the show the actual work needed to adapt the tests in
subsequent patch at the cost of breaking test_progs build for the moment.
