I believe that kvno krbtgt should obey default_tgs_enctypes but would
be willing to reconsider based on implementation complexity or others'

Another thing to consider that I don't think I like would be to always
use default_tkt_enctypes for tgts.  I don't actually think that makes
things simpler or solves any real problems.
