crossystem: add a hwid override mechanism from chromeos-config
Devices which do not use chromeos firmware (e.g., reven) do not have a
GBB section nor firmware to expose this data via ACPI/device-tree.
However, a hwid is still required for auto-update, UMA, etc.
CL:3118810 adds a new property to the schema for /:hwid-override.
This CL makes it so when that property is set, ACPI/device-tree is not
probed for the HWID, and it is instead set via cros_config.
