San Mehat fcf24fe62f vold: Add a versioned superblock to secure containers.
Add an un-encrypted superblock to the end of a secure container to
help identify the crypto cipher used. This is required in order to
provide some semblence of versioning, in case we have cause to
change the crypto type on an update - say for example switching
from software to hardware encryption, or from 128 -> a zillion
bit keys.

NOTE: This format is incompatible with previous secure containers.
After this change they will no longer be mountable.
