Tests: Generate test file listing with dmake.

Use dmake to generate a test/testfiles.pri with all the files
containing tests. The testfiles.pri is included by the test/test.pro,
which compiles the test runner. This automates the test file listing
instead of former way to hand-edit the file list.

Fixes ticket #3885 (dmake needs to create a list of test files for qmake)
