krb5: Add a verify mode for the HMAC_SHA1 checksum

Browse Source 
Add a verify operation for this checksum. If a verify operation isn't
defined, then the verify_checksum code has to dynamically allocate and
free a block of memory for the computed checksum, which can be a
significant overhead when performing bulk data encryption.
