We don't have an explicit indication of whether the root disk is
encrypted or not. For now, try to detect it and set the flag if
found.
Series-to: concept
Cover-letter:
Continue TKey development
This series adds the ability to provide a user-supplied secret to the
TKey and use that to obtain a disk-encryption key.
Expo is enhanced to support password entry and bootflows can now record
whether the root disk is encrypted or not.
Further work will enable the TKey in the UI and actually unlock an
encrypted disk.
