Bug: 1182059 Test: `./repo` still works w/out /usr/bin/python Change-Id: I1806f2ae2f8c6fe8b5f5a95fd2e50735d6e3196a Reviewed-on: https://chromium-review.googlesource.com/c/chromium/tools/depot_tools/+/2715994 Reviewed-by: Michael Mortensen <mmortensen@google.com> Commit-Queue: Mike Frysinger <vapier@chromium.org>
