proxy_getaddrinfo(): Fill in ai_socktype if requested

Browse Source 
If the application specifies a protocol but not a socket type,
normally getaddrinfo will select a corresponding protocol.

Mimic this behavior in our implementation of the function as well.
We only care about the case we're actually able to proxify
(SOCK_STREAM / IPPROTO_TCP).

Fixes proxifying pssh.
