[PATCH 2/8] unix-socket: simplify initialization of unix_stream_listen_opts

["Jeff Hostetler via GitGitGadget" <gitgitgadget@gmail.com>]

From: Jeff Hostetler <jeffhost@microsoft.com>

Change the public initialization of `struct unix_stream_listen_opts`
to be all zeroes.  Hide the default values for the timeout and backlog
values inside `unix-socket.c`.
