The gettid syscall is used in some corners of glibc and it is a fairly
harmless syscall (we already give getpid), so this change moves it to
the common policy.

Using syslog from glibc will use some syscalls we haven't seen before,
leading to the process getting killed. This change fixes that.

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.
