gpg: Change OID of Ed25519 and add Brainpool oids.

* common/openpgp-oid.c (openpgp_curve_to_oid): Change OID for
Ed25519.  Add brainpool OIDs.
(openpgp_oid_to_curve): Ditto.
--

This change is required to the change in Libgcrypt.  Note that we will
likely use a different OpenPGP algorithm ID for EdDSA and thus the
current Ed25519 implementation will not stay with us.
