socket::test::connect_timeout_unrouteable requires network interfaces

[ignatenkobrain]

Hello,

As part of packaging crates as RPMs we run tests. And recently I found out that if there are no network adapters, one of the tests is failing:

[  129s] failures:
[  129s] 
[  129s] ---- socket::test::connect_timeout_unrouteable stdout ----
[  129s] thread 'socket::test::connect_timeout_unrouteable' panicked at 'unexpected error Network is unreachable (os error 101)', src/socket.rs:902:23
[  129s] note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.
[  129s] 
[  129s] 
[  129s] failures:
[  129s]     socket::test::connect_timeout_unrouteable

Would appreciate if you could look on this issue.

Thanks for the report, but this is a crate for sockets so some tests will require the network.
