qt: Fix tofuinfo test when gpg is gpg2

* lang/qt/tests/t-support.cpp (QGpgMETest::copyKeyrings): New helper.
* lang/qt/tests/t-support.h: Declare.
* lang/qt/tests/t-encrypt.cpp: use it
* lang/qt/tests/t-tofuinbo.cpp: ditto.

--
New helper takes care of copying the correct files for either
keybox or keyring.
