When building with MIT Kerberos, pam_ksu crashes if the user doesn't have a ticket because default_principal is never populated in get_su_principal(). Change the compatibility function to use krb5_build_principal_alloc_va instead, and make its interface compatible with the equivalent Heimdal function. Despite what the comment says, we do free the default principal later in get_su_principal() so this shouldn't cause any leaks.
