sstate-cache-management.sh: fix it for downloaded file 

Fix it for the downloaded sstate cache file
* The downloaded sstate cache file is in SSTATE_DIR, and there is a
  symlink points to it, the sstate cache file should not be removed if
  the corresponding symlink is kept, it would be removed when the
  symlink is removed (with -L option).

* Fix a comment line.
