mstflint: Setting GUIDs and MACs

To set GUIDs/MACs/UID for the given device, use the 'sg' (set guids) command with the -guid(s), -uid
and/or -mac(s) flags.
4th Generation (Group I) Devices
On 4th generation/Group I devices, the "sg" command can operate on both the image file and
the image on the flash. When running the "sg" command on an image on the flash, if the GUIDs/
MACs/UIDs in the image are non-blank, the mstflint will re-burn the current image using the
given GUIDs/MACs/UIDs.
1. Change the GUIDs/MACs on a device:
# mstflint -d 41:00.0 q
