Fix DER encoder implementations for output structures "EC" and "SM2" 

These DER encoder implementations are supposed to be aliases for the
"type-specific" output structure, but were made different in so far
that they would output a "type specific" public key, which turns out
to be garbage (it called i2o_ECPublicKey()).  The "type-specific"
output structure doesn't support that, and shouldn't.

Fixes #16977
