windows agent setup failure

[chidhambaram7]

Recently we come across wpt windows agent issue where the agent was not connecting to master. To debug the issue, took RDP of windows agent and tried to run the setup script and found that internal/webpagetest.py file failed to recognise the platform and trying to run Linux routing commands.

This issue is observed after this commit.

Got the below exception while executing wptagent.py file.
