[PATCH 02/10] lei: keep client {sock} in short-lived workers

[Eric Wong <e@80x24.org>]

For non-persistent workers, there's no harm in keeping the
client socket open.  This means we can avoid dancing around
closing it in PublicInbox::LeiAuth::ipc_atfork_child.
Eventually, other WQ workers will trigger "git credential"
spawning in script/lei directly.
