[1/6] testbot/TestAgent: 'nc -q0' seems to be the default but make it explicit just in case. (resend)

[Francois Gouget]

I'm resending this patch because it belongs to a 6-parts series, not a 
12-parts one. In fact the patches are mostly conceptually independent 
but some touch the same area so they may need to be applied in the right 
order.

Also this 6-part series could probably be changed to three 2-parts 
series but that would be pretty confusing.

When the client disconnects it shuts down the ssh connection which leads 
to netcat's stdin. When that happens netcat gets an EOF and we then want 
it to exit right away rather than hang around and potentially prevent 
us from reconnecting to the testagentd server.

libvirt also uses the '-q0' option (however I believe it's mostly on 
Windows that -q0 is not the default so we should not run into this 
issue: the host we run netcat on is Unix).
