Daniel P. Berrange abd983c0e0 sockets: strengthen test suite IP protocol availability checks
Instead of just checking whether it is possible to bind() on a socket, also
check that we can successfully connect() to the socket we bound to. This
more closely replicates the level of functionality that tests will actually
use.
