Cachefilesd module updates
The module was incomplete because I was not confident about various rules
implemented in the Fedora policy.
The files_create_all_files_as_is(cachefilesd_t) interface call was a bad idea.
Instead it just needs to
maintain files in the cache with the cachefiles_cache_t type.
The process associated with cachefiles_kernel_t is a kernel thread (kworker)
