aklog: retry getting tokens for KRB5_KT_NOTFOUND error
If we're creating tokens with -keytab and our AFS service principal is
afs@<cellname>, we'll first try creating tokens with
afs/<cellname>@<cellname> and krb5_kt_get_entry will fail with
KRB5_KT_NOTFOUND. Since we do not retry for KRB5_KT_NOTFOUND error, we
will not get tokens. So in order to get tokens for principal
afs@<cellname> we should retry for KRB5_KT_NOTFOUND error. Thanks to
jpjanosi@us.ibm.com for finding this issue and suggesting a fix.
