sockets: Prepare vsock_parse() for flattened SocketAddress
I'm going to flatten SocketAddress: rename SocketAddress to
SocketAddressLegacy, SocketAddressFlat to SocketAddress, eliminate
SocketAddressLegacy except in external interfaces.
vsock_parse() returns a newly allocated VsockSocketAddress. Lift the
allocation from vsock_parse() into its caller socket_parse() to
prepare for flattening SocketAddress.
