Add EC curve tag to keymaster1 SoftKeymaster1 attestations.

Key attestations for EC keys must include the EC curve tag, which didn't
exist in keymaster1. When SoftKeymaster produces attestations for
keymaster1 keys, it must deduce the curve (based on key size; the
mapping is unambiguous) and add the curve tag to the attestation.
