Enable some mach commands to be run with python3
This change finally enable the following commands to be run with python3:
* `build`
* `test-unit`
* `package`
As previously explained, `test-tidy` will require more work in the wpt repository directly. Maybe `test-tidy --no-wpt` is achievable relatively quickly though.
For possible remaining bits that might need to be worked on, see https://github.com/servo/servo/issues/23607
