Android: activate tst_QLibrary

On Android we demand the libraries to always start with "lib" and
end with ".so" extension. Also Android does not support versioned
libraries.

This patch updates CMakeLists.txt to fulfill these requirements,
and also omits some unsupported test cases.

This allows to enable this test for Android in CMakeLists.txt
