s3:libads: ads_krb5_chg_password() should always use the canonicalized principal
We should always use krb5_get_init_creds_opt_set_canonicalize()
and krb5_get_init_creds_opt_set_win2k() for heimdal
and expect the client principal to be changed.
There's no reason to have a different logic between MIT and Heimdal.
