Doesn't check if powershell.exe is in the PATH

[jasonwbarnett]

Version:

v3.11.2

Environment:

Windows Server 2012R2
Chef Client v4.10.9

Scenario:

Upgrade Chef Infra Client using the chef_client_updater cookbook.

Steps to Reproduce:

Remove everything, but C:\opscode\chef\bin from your system PATH.

Expected Result:

I would expect mixlib-install to throw an exception OR add powershell.exe to the PATH (temporarily, not permanently).

Actual Result:

It returns an array of Mixlib::Install::ArtifactInfo which include things for all OSes.
