Cleanup CMake MSYS2 build

ctest did run the tests, however the tests in scripts
mostly did not pass:

 - test_output.sh
 - test_log_output.sh
 - test_tap_output.sh
 - test_check_nofork_teardown.sh

Those will need to be investigated at some point. In
the meantime, the check_check test run successfully.
