Cong Lin 8c0e7f2ba3 Factory extraction tool: Use device info from OS property when TEE returns empty
Similar change is merged to widevine internal tool: ag/22824076

Some mandatory device info fields like manufacturer can be empty string
when returned from TEE on devices which have not been provisioned with
attestation IDs.

The extraction tool also needs to check for empty string in the
response, and if so, populates the field with Android property values.

Test: extracting device info from new Pixel EVT 1.1 and uploading
