tox.ini update: Fix breakage caused by src/ext move, add 32-bit linux environments and other architectures supported by docker #29143
Description
#29053 added tox.ini to support testing the sage distribution in isolated environments via docker.
In 9.1.beta6, the generated docker files do not work due to #21785.
This ticket fixes it and also adds linux environments for various other architectures supported by docker (see https://github.com/docker-library/official-images#architectures-other-than-amd64).
Examples:
$ tox -e docker-debian-buster-standard-i386
$ tox -e docker-ubuntu-bionic-standard-arm64
$ tox -e docker-ubuntu-bionic-minimal-armhf
$ tox -e docker-fedora-31-standard-arm64v8 # Docker for Mac only
$ tox -e docker-ubuntu-latest-standard-s390x # Docker for Mac only
(The last two work with macOS Docker Desktop because it has binfmt_misc with qemu enabled.)
