subprocess: maintain a thread for fork/exec
If SubprocessServer::Init() is called from a short-lived thread, because
it does a fork/exec, the subprocess will silently be reaped when the
thread exits.
Specifically, we saw this happening upon initializing the
CatalogManager, which happens in a short-lived thread, when starting up
the Ranger client. This surfaced as us getting an EOF from the
subprocess receiver thread.
