fix travis build issue

This morning, I found that all the c++ build job related to "TOOLSET=asan" returns an error, even we try to rebuild the old jobs which already passed:

Debug w/ @springmeyer, we thought this is a new Travis error due to a new leak in node.js.

To fix this issue we need to add echo "leak:node::Start" >> ${SUPPRESSION_FILE} in scripts/sanitize.sh

OR see this PR https://github.com/mapbox/node-cpp-skel/pull/156/files.

This will fix the issue.

Commencez par scripts/sanitize.sh et les jobs Travis utilisant TOOLSET=asan. Comparez les entrées de suppression du sanitizer avec la pull request node-cpp-skel référencée, puis relancez ou inspectez le build C++ ASAN concerné ; c’est terminé lorsque les jobs ASAN s’exécutent jusqu’au bout sans l’échec de fuite Node.js signalé.
