cloudinit: move dmi functions out of util (#622)

This just separates the reading of dmi values into its own file.

Some things of note:
 * left import of util in dmi.py only for 'is_container'
   It'd be good if is_container was not in util.
 * just the use of 'util.is_x86' to dmi.py
 * open() is used directly rather than load_file.
