ngtcp2: avoid building examples on FreeBSD due to Linux-specific socket APIs

Browse Source 
The ngtcp2 examples use Linux-specific socket options (IP_PKTINFO,
IPTOS_ECN_MASK, IP_RECVTOS) for packet metadata and ECN support that
are not available on FreeBSD.

Enable ENABLE_LIB_ONLY on FreeBSD to skip examples while building
the core library.
