    gsocket: test if family is <= 0, not < 0
    
    If all members of GSocketFamily are supported on the platform, then
    all of its values will be positive, and so the enum might become
    unsigned, in which case testing for "family < 0" might cause warnings.
    But we want to return an error if family == 0 (aka
    G_SOCKET_FAMILY_INVALID) anyway, so just tweak the test accordingly.
