MINOR: quic: implement build options report

Define a new function quic_register_build_options(). Its purpose is to
register a build options string for QUIC features which is reported when
using haproxy -vv.

This will allow to easily determine if connection socket-owner mode and
GSO are supported or not. Here is the new filtered output :

$ ./haproxy -vv|grep '^QUIC:'
QUIC: connection socket-owner mode support : yes
QUIC: GSO emission support : yes
