[ruby/openssl] pkey: avoid calling i2d_PUBKEY family on an incomplete key
Call ossl_pkey_check_public_key() to ensure that EVP_PKEY_missing_parameters() passes. This check should be cheap.
DSA#{to_der,to_pem,export,to_s} and PKey#{public_to_der,public_to_pem} cause a segfault if the receiver is an empty DSA instance with no parameters set.
