QUIC: using native TLSv1.3 cipher suite constants.
After BoringSSL aligned[1] with OpenSSL on TLS1_3_CK_* macros, and
LibreSSL uses OpenSSL naming, our own variants can be dropped now.
Compatibility is preserved with libraries that lack these macros.
Additionally, transition to SSL_CIPHER_get_id() fixes build error
with LibreSSL that doesn't implement SSL_CIPHER_get_protocol_id().
