whitelist some globals under Windows for node >=v0.8.x

Hello,

Node.js leaks some specifics globals under Windows since v0.8 (COUNTER_NET_SERVER_CONNECTION, COUNTER_NET_SERVER_CONNECTION_CLOSE, COUNTER_HTTP_SERVER_REQUEST, etc.) and they need to be whitelisted.

Also, the DTrace globals leaks on Windows since v0.8 (since v0.10 on Linux) and they need to be whitelisted as well.

This patch should fix all of these.
