 I believe WordPress should use the system tmp directory as first
 preference temp directory in ```get_temp_dir``` if ```WP_TEMP_DIR```, is
 not defined. It just seems… odd… to use ```wp-content``` in preference to
 the proper, managed, temp directory.

 Some historical context on introducing ```get_temp_dir```: #5984
