git diff --name-only will only report if EXISTING files have changed, but will be nullstring for new files... we need to use git status -s to get status of new files added.

Looks like lots of jenkinsfiles use only git diff to check if there's anything to commit... and so – for the case of jwtproxy and possibly others – we're failing to add new files.

Fix for jwtproxy sync should be this:

But we should verify all builds are also syncing all new files too.
