Qt: Add encryption test and refactor testsuite

* lang/qt/tests/Makefile.am: Add t-encrypt and t-support.
* lang/qt/tests/t-support.cpp, lang/qt/tests/t-support.c (QGpgMETest):
New. Class to handle common cleanup / init.
* lang/qt/tests/t-keylist.cpp,
lang/qt/tests/t-keylocate.cpp,
lang/qt/tests/t-ownertrust.cpp,
lang/qt/tests/t-tofuinfo.cpp: Inherit QGpgMETest.
* lang/qt/tests/t-encrypt.cpp: New. Test Symetric and Asymectric
encryption. Mixed encryption test is disabled.
