[BUG] File URL on Windows

[Luigicube]

Bug description
Using the "local sdist archive" workflow on Windows yields an URL that is not compatible with conda-build, see:
"source:
url: file://D:\temp\myPackage-0.0.2.tar.gz"
instead of "source:
url: file:///D:/temp/myPackage-0.0.2.tar.gz"

To Reproduce
Steps to reproduce the behavior:

1. Using the "local sdist archive" workflow on Windows, e.g. grayskull pypi ./pytest-5.3.5.tar.gz
2. Try using conda-build on the generated meta.yaml

Expected behavior
conda-build works - or at least manages to "download" the source.
