a60744b42e crosvm: use seqpacket rather than datagram sockets 
The advantage of seqpacket is that they are connection oriented. A
listener can be created that accepts new connections, useful for the
path based VM control sockets. Previously, the only bidirectional
sockets in crosvm were either stream based or made using socketpair.

This change also whitelists sendmsg and recvmsg for the common device
policy.
