Fix git source regression (#2699)

## Changes
Fix git source regression. Jobs using the `git_source` feature shouldn't
have their paths normalized because they are referring to files in git
repositories, not local paths.

There is still a problem with how libraries and other paths are
translated, but this has been a problem for a long time and hasn't
regressed recently.

Fixes #2697

## Tests
Acceptance tests
