    utils/trackertestutils: Make it usable by other projects
    
    This command improves the tracker-testutils-2.0 pkg-config package,
    by adding a `command=` variable.
    
    The idea is that projects using Tracker can use this as a way to
    sandbox their test suites from the user's real Tracker data.
    
    In your meson.build file you would do something like this to locate
    the script and run your test.
    
        python3 = find_program('python3')
        trackertestutils = dependency('tracker-testutils-2.0')
    
        tracker_sandbox_command = find_program(trackertestutils.get_pkgconfig_variable('command'))
    
        test('myapptest', tracker_sandbox_command,
          args: ['--index-tmpdir', my_app_test_executable])
    
    This would ensure that XDG_CACHE_HOME and XDG_DATA_HOME point to a
    temporary directory, separate from any real Tracker index data that the
    current user might have inside their XDG cache & data directories.
