psutils: Add --get-model option

Add a --get-model command line option to the psutils tool.  This option
obtains the PSU model using information in sysfs.

Supports both methods of obtaining information about a PSU:
* psu.json file
* D-Bus

Tested:
* Verified --get-version still works
  * With psu.json file
  * Without psu.json file
* Verified new --get-model property works
  * With psu.json file
  * Without psu.json file
  * Tested all error paths
* See the following gist for the complete test plan:
