    libide/threading: always merge down mapped FD
    
    Even if the source_fd is -1, we still want to keep merging it to a lower
    layer so that it ends up in the final IdeUnixFDMap.
    
    This also fixes a situation with a few runtimes that were not silencing
    stdout when running `which` even though they expected to.
