Disable encrypted backups

Encrypted backups are poorly implemented (both by TWRP for padding a
password with zeros to achieve an AES key and openaes for using
non-standard CBC) and not to be trusted. Do not give users a false
sense of security by offering this option. Remove the ability to use
openaes to encrypt backups, but still allow already openaes-encrypted
backups to be restored.
