The purpose of the code is to make a new temporary folder with the
necessary resources used to package Linux. Before this, the package
was built based on a modified target directory. By using a temporary
folder, it removes the need to rebuild Servo every time it gets
packaged for Linux.
Create .tar.gz package deterministically using Python's "tarfile"
<!-- Please describe your changes on the following line: -->
A development of #12108, creates a .tar.gz package using the `tarfile` and `gzip` modules, without external dependencies. Fixes#11981.
Also this fixes the issue when the existing `resources/` directory didn't allow to create a new package and failed with "File exists" error.
