Revert "build: Adds win_delay_hook so iojs runs with alias."

[xzyfer]

This PR reverts commit 579baf3.

This is causing a lot of issues for people trying to install node-sass on windows. Two main culprits are proxy blocking git ports, or the local system not having git installed.

Fixes #939.
Fixes #933.
Closed #931.

As an alternative, what about adding iojs.exe or atomwhateceritscallednow.exe binaries to the matrix?

[xzyfer]

The troubleshooting guide has an issue for the iojs.exe issue. I don't think there is an alternative since Windows installs atm are broken.

Reverting this makes them less broken.

Windows install are not broken.
We don't need alternative solution to the problem which tons of people discussed in io.js issue tracker and devised this working tangible solution.
Secondly, until we hear back from @rvagg regarding rvagg/archived-pangyp#5, we can revert back pangyp to npm version. For the release, I will build the binaries locally with the delay load fix. So the issue is very much contained and effect only those who use io.js on windows && manually building node-sass binary.

More specifically, they're broken for Windows users without git installed.
