MINOR: quic: activate QUIC traces at compilation

Implement a function quic_init_stdout_traces called at STG_INIT. If
ENABLE_QUIC_STDOUT_TRACES preprocessor define is set, the QUIC trace
module will be automatically activated to emit traces on stdout on the
developer level.

The main purpose for now is to be able to generate traces on the haproxy
docker image used for QUIC interop testing suite. This should facilitate
test failure analysis.
