Fixed failure of tst_xmlpatterns due to Qt plugin loading changes

The test tries to verify that the xmlpatterns command outputs nothing on
standard error.  Qt makes this difficult by warning about some plugins
(unrelated to xmlpatterns) using the old plugin API.

Those plugins should be updated, but the warnings are irrelevant to
xmlpatterns, so ignore them.
