    Make ksu work with prompting clpreauth modules
    
    Commit 5fd5a67c5a93514e7d0a64425baa007ad91f57de switched ksu from
    using krb5_get_in_tkt_with_password() to
    krb5_get_init_creds_password(), but did not supply a prompter
    argument.  Pass krb5_prompter_posix so that clpreauth modules can
    prompt for additional information during authentication.
    
    (cherry picked from commit 23a16fb5eac733880e34a770882ed17b93b5d66c)
