aklog: Probe for libasn1 on heimdal

aklog uses encode_EncTicketPart and some other encode_* ASN.1 routines
when we're building against heimdal. Our krb5 autoconf logic from
c-rra-util is not guaranteed to include libasn1 in KRB5_LIBS, since
it's not required for functions in the krb5 API. So, specifically test
for it.
