futility: updater: Change 'whitelabel_tag' to 'customlabel_tag'

Support new VPD name 'customlabel_tag' for the custom label program.
For shipped devices (firmware is already locked and write protected) we
still support the legacy name.

The quirk 'allow_empty_wl_tag' also renamed to
'allow_empty_customlabel_tag'.
This is usually not recommended, but given no devices have used this
quirk in the CBFS quirks, it should be fine to change the quirk name.
