Qt: Add a unit test for qgpgme

* configure.ac: Configure test Makefile.
* m4/qt.m4: Look up Qt5Test flags.
* lang/qt/tests/t-keylist.cpp: New. Simple keylist check.
* lang/qt/tests/Makefile.am: New. General test framework.

--
This test mostly checks that it basically compiles / works and
adds a test framework.
