Trac #30944: tox: Improve local-sudo-ubuntu-standard

As a follow up to #30923, we improve the `local-sudo-...` environments
as follows:
- Provide alternative environments `local-root...`, which assume that we
are already root, removing the `sudo` requirement (which is not
installed on github actions and not needed there)
- Use `configure --enable-build-as-root` for `local-root`
- Add `DEBIAN_FRONTEND: noninteractive` to the installation of packages
via `apt get` (otherwise installation of `tzdata` blocks CI)
- Make `tox -e local-sudo-standard -- config.status` only build
`config.status` instead of also invoking `make base-toolchain` (which is
run as the required first step of the Sage build system before something
like `make numpy` can be run; see #30721).
