ProcessController: Report kernel memory and fix some TODOs.

Browse Source 
* Restore logic for excluding app_server side of bitmaps
   (though this may not work for server-cloned areas, only
   server-allocated ones.)

 * Leave TODO in place for media buffers.

 * Add all kernel-writable areas of the system (kernel) team
   to writable memory, but exclude the block_cache.

Fixes display of kernel memory information in ProcessController's
memory usage menu.
