MINOR: cli/show_fd: report local and report ports when known

Browse Source 
FD dumps are not always easy to match against netstat dumps, and often
require an lsof as a third dump. Let's emit the socket family, and the
local and remore ports when the FD is an IPv4/IPv6 socket, this will
significantly ease the matching.
