cryptfs: Clarify sizing of intermediate key

Some parts of the code were intermingling constants for the master
key and the intermediate key.  That works at the moment because
these are the same size.  But we'll be introducing logic allowing
different sized master keys, while keeping the intermediate the
same.  To aid that introduction, we use separate constants for
the intermediate key.
