In general, WSAEWOULDBLOCK can be mapped to EAGAIN as done by
socket_error() (or EWOULDBLOCK). But for connect() with non-blocking
sockets, it actually means the operation is in progress:
https://docs.microsoft.com/en-us/windows/win32/api/winsock2/nf-winsock2-connect
"The socket is marked as nonblocking and the connection cannot be completed
immediately."
(this is also the behaviour implemented by GLib GSocket)
This fixes socket_can_bind_connect() test on win32.
