[net] DiagnosticSocket wrapper for sock_diag API
This patch introduces DiagnosticSocket wrapper for sock_diag() netlink
subsystem [1][2]. The primary intention behind DiagnosticSocket is to
fetch information on the RX queue size for a listening IPv4 TCP socket.
A follow-up patch will use this new facility to populate a new
server-level metric: that's to track connection request backlog for a
Kudu server's RPC socket (a.k.a. listened socket backlog, pending
connections queue, etc.).
Since netlink is a Linux-specific API/subsystem, the DiagnosticSocket
API is available only on Linux, correspondingly.
This patch includes a few unit tests to provide basic coverage
for the newly introduced functionality.
