quic: disable building ngtcp2 examples

The ngtcp2 client and server examples are built with the intention of
using them as reference implementations for future quic tests.
However, as of ngtcp2 1.22.0, these examples require c++-23 libraries,
which doesn't match the current Node.js build requirements.
