Pullup to 1.7-branch is only for the test case, as krb5-1.7 behaved
correctly for these checksums.

Fix regression in MD4-DES and MD5-DES keyed checksums.  The original
key was being used for the DES encryption, not the "xorkey".  (key
with each byte XORed with 0xf0)

Add a test case that will catch future regressions of this sort, by
including a verification of a "known-good" checksum (derived from a
known-to-be-interoperable version of the implementation).
