Remove unsafe principal parsing from Leashdll
In Leash_int_kinit_ex(), remove the code to parse and reassemble the
principal name; it has no length checks and could overflow
stack-allocated buffers if a long principal name is supplied. This
parsing code was used to perform krb4 fallbacks if getting tickets via
krb5 failed, and is no longer useful.
Discovered by Aisle Research.
