Mårten Nordheim 27f52942b4 tst_QTcpSocket: stabilize connectToHostError 
It's not _wrong_ to time out when connecting to something unreachable
(it's just a different way of handling it) so we shouldn't fail when
this happens either.

In local testing (windows) it times out after 8 seconds, so bump
the timer to 10 seconds. On systems where it's faster there'll be
no difference as long as things don't go wrong.

Pick-to: 6.0
Fixes: QTBUG-89089
