Zach Reizner	2ea297ac76	seccomp: add sendto, writev, and readv to common seccomp policies ... Using syslog from glibc will use some syscalls we haven't seen before, leading to the process getting killed. This change fixes that.

Zach Reizner	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.
