    Don't generate installed test files when not enabled
    
    These files are not needed except when installed tests are enabled, so
    they should not be generated at all by default.
    
    This is good to do for its own sake, but also works around some weird
    behavior of meson that has resulted in these files being installed even
    when installed tests are disabled.
