tox.ini update: Fix breakage caused by src/ext move, add 32-bit linux environments and other architectures supported by docker

[mkoeppe]

#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.)

This works on macOS because it is running everything in a virtualbox.

I haven't succeeded in getting it to work on github actions yet. last attempt: https://github.com/mkoeppe/sage/runs/422184737?check_suite_focus=true

The branch is no longer on top of #29104 (homebrew).

Needs review.
