Add BIOS attribute tag in backup_restore JSON

This commit adds a tag "isUsedForBiosAttributeBackup" to the "backupMap"
in backup_restore JSON files. This tag will be useful for identifying
keywords which are used for backing up BIOS attributes in VPD.
This tag is required for implementation of --syncBiosAttributes option
in vpd-tool --mfgClean.

Test:
```
- install bitbaked image on an Everest system
- reboot, after reboot, ensure that backup restore feature of
vpd-manager runs as usual
```
