Use QSslServer in certificate test

We had our own implementation for the HTTPS server.
However, the way it worked involved adding for every
incoming connection a socket to the list of pending
connections, which resulted in unnecessary logging noise
due to socket connect/disconnected signals during
the SSL handshake negotiations. It also resulted in
memory leaks.

Since 6.4 we have now QSslServer which adds socket to the
pending connection list only after encryption got established.

Pick-to: 6.4
