Fixed qsslsocket_onDemandCertificates_{static,member}

This test had been XFAILing since August 2011, but recently started to
XPASS, possibly due to changes in the SSL setup on the tested host
(qt.nokia.com).

Removed QEXPECT_FAIL and replaced qt.nokia.com with
codereview.qt-project.org as a host expected to have working SSL.  (If
SSL on the latter were broken, it would immediately be detected by
any attempts at git over HTTPS.)

SSL setup can be verified as working by:

  openssl s_client -CApath /etc/ssl/certs \
    -connect codereview.qt-project.org:443 </dev/null
