WebSocket Pepper API: use net::IsPortAllowedByDefault() to validate port

Enable port validation because net::IsPortAllowedByDefault() was exported now

This change is originally included in http://codereview.chromium.org/8558017/.
At that time, net::IsPortAllowedByDefault() was not exported out of shared
library. Then, shared build failed and the check is temporally disabled.

Now, net:IsPortAllowedByDefault() was exported.
I'd like to re-enable this port check function.

Why did you move the namespace? It would seem better to have them within the
unnamed namespace, unless that's causing you some kind of problem.

Yuta suggest me this change because constant variables are handled as static, or
private in the file by default in C++.
So, we can just place them out of unnamed namespace.
