bpf, selftests: Fix test_maps now that sockmap supports UDP

UDP socket support was added recently so testing UDP insert failure is no
longer correct and causes test_maps failure. The fix is easy though, we
simply need to test that UDP is correctly added instead of blocked.

Fixes: 122e6c79efe1c ("sock_map: Update sock type checks for UDP")
