Kernel: Truncate addresses stored by getsockname() and getpeername()

Browse source 
If there's not enough space in the output buffer for the whole sockaddr
we now simply truncate the address instead of returning EINVAL.

This patch also makes getpeername() actually return the peer address
rather than the local address.. :^)
