QUIC: fixed OpenSSL compat layer with OpenSSL master branch. The layer is enabled as a fallback if the QUIC support is configured and the BoringSSL API wasn't detected, or when using the --with-openssl option, also compatible with QuicTLS and LibreSSL. For the latter, the layer is assumed to be present if QUIC was requested, so it needs to be undefined to prevent QUIC API redefinition as appropriate. A previously used approach to test the TLSEXT_TYPE_quic_transport_parameters macro doesn't work with OpenSSL 3.2 master branch where this macro appeared with incompatible QUIC API. To fix the build there, the test is revised to pass only for QuicTLS and LibreSSL.
