Attempt to set the proper uid/gid/contexts on new files and dirs

Files and folders that we create during backups, copy log, or MTP
operations often do not have the proper uid/gid/contexts assigned.
We will attempt to read the proper contexts from the settings
storage path and assign those same contexts to any files or dirs
that we create.
