Cope with previously-emulated keys

If a device has upgraded Android versions then the KeyMint device
may also have been upgraded.  If that's the case, then there may
be keyblobs that were created in software on the old device, because it
didn't support some feature.

Watch out for these keys, and if encountered, try to import them into
the current KeyMint device:

- extract the key material from the key blob
- add PKCS#8 wrapping for import
