chromium: delete unused paths in source tarball

to stay below hydra limit. At the time of writing, the hydra.nixos.org's output limit is 3 GB. The latest chromium tarball, however, is slightly above that. To work around this, recompress the original `tar.xz` into a `tar.zstd` and delete two unreasonably big and unused directories. Bringing it down to roughtly 2.2 GB. Unfortunately, this change breaks the `update.py` script. Resolves the current channel-blocker.
