    Restore test coverage for old session key types
    
    Commit 1b57a4d134bbd0e7c52d5885a92eccc815726463 made the KDC stop
    issuing des3 and rc4 session keys by default.  To make the des3 and
    arcfour passes of the test suite work, it added aes256-sha1 to the
    permitted enctypes for those passes.  Negotiating AES session keys
    reduces coverage of pre-CFX GSSAPI code and other uses of the older
    enctypes.  Instead set the enable_des3 and enable_rc4 variables.
