Subject: [PATCH bpf] selftests/bpf: Mark SYN cookie test skipped for UDP sockets

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.

Fixes: 7ee0d4e97b88 ("selftests/bpf: Switch reuseport tests for test_progs framework")
