Michael Pratt b23b36e701 Add NETLINK_KOBJECT_UEVENT socket support
NETLINK_KOBJECT_UEVENT sockets send udev-style messages for device events.
gVisor doesn't have any device events, so our sockets don't need to do anything
once created.

systemd's device manager needs to be able to create one of these sockets. It
also wants to install a BPF filter on the socket. Since we'll never send any
messages, the filter would never be invoked, thus we just fake it out.

Updates #1119

Ian Lewis 470997ca99 Allow for zero byte iovec with MSG_PEEK | MSG_TRUNC in recvmsg.
This allows for peeking at the length of the next message on a netlink socket
without pulling it off the socket's buffer/queue, allowing tools like 'ip' to
work.

This CL also fixes an issue where dump_done_errno was not included in the
NLMSG_DONE messages payload.

Andrei Vagin af90e68623 netlink: return an error in nlmsgerr
Now if a process sends an unsupported netlink requests,
an error is returned from the send system call.

The linux kernel works differently in this case. It returns errors in the
nlmsgerr netlink message.

Nicolas Lacasse d2f8586a1f Kokoro: Build all packages as part of presubmit.
We now build all packages (including //test/...) with RBE as part of the Kokoro
presubmit.

The tests do not yet use RBE, because there are some failures. The Golang unit,
integration, and image tests still run locally.

The syscall test suite needs even more work to make it pass on RBE. Those will
be enabled in follow-up CLs. They currently are not enabled at all on Kokoro.
