Use crypton-asn1-types/encoding when +crypton flag is set

crypton-x509 >= 1.8.0 depends on crypton-asn1-types rather than
asn1-types. Having both in scope causes a typeclass conflict on
ASN1Object. Move asn1-types and asn1-encoding into the else branch
and add crypton-asn1-types and crypton-asn1-encoding to the
if flag(crypton) branch.
