[PATCH 2/4] tests/test-util-sockets: Skip test on non-x86 Travis containers

[Philippe Mathieu-Daudé]

Similarly to commit 4f370b1098, test-util-sockets fails in
restricted non-x86 Travis containers since they apparently
blacklisted some required system calls there.
Let's simply skip the test if we detect such an environment.
