Philip Withnall 6751424bbe tests: Skip GSocket tests if setting up a server fails
There are various reasons why setting up a server might fail; it
reliably fails on AWS with IPv6 addresses (are we binding to the right
address?). Since we’re trying to test GSocket as a client, skip tests
where that happens.
