KEYS: asymmetric: Fix ECDSA use via keyctl uapi
When support for ECDSA keys was added, constraints for data & signature
sizes were never updated. This makes it impossible to use such keys via
keyctl API from userspace.
Update constraint on max_data_size to 64 bytes in order to support
SHA512-based signatures. Also update the signature length constraints
per ECDSA signature encoding described in RFC 5480.
Fixes: 299f561a6693 ("x509: Add support for parsing x509 certs with ECDSA keys")
