ktutil: Print the numeric enctype if krb5_enctype_to_string() fails

Sadly krb5_enctype_to_string() fails when des-cbc-crc encyrption
type is removed, leaving a failure the operate rather than
falling back to anything useful.

So fall back to printing 3 in the absense of anything more
useful.  A future fix could be to hard-code this mapping
in the smb_krb5_enctype_to_string() wrapper.
