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 Bug: 276958001 Change-Id: I6e1b3dee8ffcd991335bc50b59a0c80f030cdc79
