    libc - Fix intermediate path elements if used in shm_open()
    
    * Our shm_open() places the path relative to /var/run/shm, but if
      the directory structure for miscellaneous prefixes (such as
      "/tmp/blahblah", "/dev/shm/blahblah", etc) do not exist under
      /var/run/shm then shm_open() fails when it should not.
    
    * Change shm_open() to automatically create any intermediate directory
      elements under /var/run/shm/ that are missing.  The elements will
      be created mode 1777.
    
    * Fixes chromium-90 and any other packages that still use directory
      prefixes in shm_open() calls.
