(#105) add localbuild upload

[corbob]

Description Of Changes

Allow local build to "upload" artifacts.

Motivation and Context

When running locally, the only way of knowing what might be uploaded to Team City artifacts is to read through the output to see where we say we would have except for it being local.

Testing

1. Copied to chocolatey/choco repository
2. Ran build script for chocolatey/choco repo
3. Verified that code_drop directory contained Artifacts with the files expected to be there.
