test: add test-spawn-cmd-named-pipe

[orangemocha]

Adding a Windows test to verify that a node process spawned via
cmd with named pipes can access its stdio streams.

Ref: nodejs/node-v0.x-archive#7345

This test was orphaned in joyent/node:master. It is still useful.

[cjihrig]

Can you remove this section.

[orangemocha]

Thanks @cjihrig for all the feedback! I will revamp this test according to your suggestions.

Can the Copyright notice really be removed? I don't think so. Even with a permissive license, one of the clauses is to preserve the copyright notice.

[cjihrig]

Yea, the copyright in all the files was removed a long time ago in io.js. I'm not a lawyer, but I think I remember something about only needing the license in the root of the project.

[orangemocha]

Ok, I'll take your word for it.

[thefourtheye]

Please use the format as in #2109

[orangemocha]

Updated. PTAL.

[cjihrig]

The commented out console.log()s should probably go. You could optionally change a few lets to consts. Other than that, LGTM if the CI is happy.

[thefourtheye]

Const

[orangemocha]

Updated according to feedback. Thanks again for all the help! Much more slick now 👍
