discover/network: Allow for arbitrary-sized netlink messages
Currently, we drop any netlink data beyond our 4096-byte buffer. This
means that we can only parse a limited number of network interfaces.
This change uses recvmsg with MSG_PEEK to determine the size of an
incoming netlink message before doing the actual recvmsg. This way, we
can realloc our buffer to suit.
