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.
Issue #769
