Relocate ECParameters_dup() to ec_asn1

jsing rightly points out that this has nothing to do with ASN.1, but
ec_lib.c has no EC_KEY knowledge otherwise (it's about groups and points)
and moving it to ec_key.c is also not satisfactory since the weird
d2i/i2d for ECParameters don't belong there either.

no objection from jsing
