This simplifies and optimizes getting container images used for tests.
Currently, we have three different ways of getting images:
1. (for hello-world) the image is in this repo under tests/integration/testdata.
2. (for busybox) download it from github (the repo that is used for
preparing official Docker image) using curl.
3. (for debian) download from Docker hub, using skopeo and umoci.
To further complicate things, we have to do this downloading in multiple
scenarios (at least 4): locally, in github CI, from Dockefile, inside a
Vagrant VM. For each scenario, we have to install skopeo and umoci, and
those two are not yet universally available for all the distros that we
use.
Yet another complication is those images are used for tests/integration
(bats-driven tests) as well as for libcontainer/integration (go tests).
The tests in libcontainer/integration rely on busybox being available
from /busybox, and the bats tests just download the images to a
temporary location during every run.
It is also hard to support CI for other architectures, because all
the machinery for preparing images is so complicated.
This commit is an attempt to simplify and optimize getting images,
mostly by getting rid of skopeo and umoci dependencies, but also
by moving the download logic into one small shell script, which
is used from all the places.
Benefits:
- images (if not present) are only downloaded once;
- same images are used for both kind of tests (go and bats);
- same images are used for local and inside-docker tests
(because source directory is mounted into container);
- the download logic is located within 1 simple shell script.
[v2: fix eval; more doc to get-images; print URL if curl failed]
[v3: use "slim" debian, twice as small]
[v4: fix not using $image in setup_bundle]
[v5: don't remove TESTDATA from helpers.bash]
[v6: add i386 support]

The fedora job usually completes within 15-16 minutes,
and the centos-7 one needs 7-8 minutes.
Set the timeouts to twice those values.

Github Actions execution environments lack tty, which is needed for
integration tests. We have used script utility before to provide a fake
tty, but it appears to be buggy on CentOS 7.
Since we use ssh anyway to access Vagant VM, add -tt to forcefully
allocate a tty.
Apparently, neither "TERM=xterm" nor "stty size" is needed for
any tests to work, so remove those, too.
Finally, unit tests do not need a terminal, so remove the "script"
from those.

This is Ubuntu 20.04 so cgroup v1 testing only :(
The upside is, it's pretty fast (currently all the tests finish
within 5 minutes).
rootless tests take longer time so we run them in parallel
with non-rootless ones. Also, to balance the time, we run
unit tests when rootless is not set. IOW, 'rootless' in job
name means it's only rootless integration tests, and no rootless
means it's unit tests, integration tests with fs driver, and
integration tests with systemd driver.
Note, `script` is used to run integration tests to provide a tty
(which by default is not available on gh actions).
