Fix regression that caused waitForXXX(-1) to fail.

Regression was introduced by 8d4cd52b6981a4e6deea7fdb77f56e40c4f3e6ba
when it failed to check when msecs == -1. This manifested visibly in KDE
failing to connect to any SSL site -- kioslaves are synchronous and use
waitForXXX(-1) (in this particular case, waitForEncrypted, which calls
waitForReadyRead).

Also, take the opportunity to convert these tests in QTcpSocket to use
port 80 (a defined service in the test server) instead of port 22.
