Title: check an availability of UNIXSocket and UNIXServer

Hello,

I tries to use net-ssh on Windows environment and it works almost fine, thanks.
However, local forwarding could not work due to lack of UNIXServer.
I'm not good at Windows, but I can understand that the UNIXServer is not available on it.
Fortunately, it appears only one situation to determine the argument type on
Net::SSH::Service::Forward#local, and it is avoidable.
In addition, test_forward_local_unix_socket_to_remote_port on test/manual/test_forward.rb
is using UNIXSocket, and its helper method create_local_socket is using UNIXServer.

Thanks again!
