Add tests for missing socks4 and socks4a forwarders

The code paths are different than for socks5 and the recent
memory leak in socks5_connect() was only detected due to the
already existing test.

Currently no such leaks exist in socks4_connect() but I may
add some in the future and would prefer to know about it.
