In case swap cgroup control is not available, the "event oom" test gives
the following error:
> # not ok 30 events oom
> # (in test file tests/integration/events.bats, line 134)
> # `[ "$status" -eq 0 ]' failed
> # <....>
> # runc run -d --console-socket /tmp/console.sock test_busybox (status=1):
> # time="2020-05-29T02:10:20Z" level=warning msg="signal: killed"
> # time="2020-05-29T02:10:20Z" level=error msg="container_linux.go:353: starting container process caused: process_linux.go:437: container init caused: process_linux.go:403: setting cgroup config for procHooks process caused: failed to write \"33554432\" to \"/sys/fs/cgroup/memory/test_busybox/memory.memsw.limit_in_bytes\": open /sys/fs/cgroup/memory/test_busybox/memory.memsw.limit_in_bytes: permission denied"
When I try to run the test without setting the swap limit, the shell
process is still getting killed, but the test hangs. I am not sure what
the reason is, but realistically this test is hard to perform without
the swap limit, so let's require cgroup swap for it.

Those needs to be run on the (Vagrant Fedora 31) host
(since we need real systemd running), and so we have
to have all the tools needed to compile runc and run
the tests.
The good news is Fedora packages a decent and recent release
of bats-core (1.1.0), which we can use (Debian does not),
and we can also use golang (currently 1.13.9) from Fedora.
The bad news are
1. Currently cgroups tests are only working with
RUNC_USE_SYSTEMD=yes (addressed by #2299, #2305)
2. Tests in events.bats do not work (need cgroupv2
memory.events support)
3. Fedora 31 image is 6 months old (and has broken
container-selinux policy) so we need `dnf update`,
which adds ~5 min to test time.
[v2: add -t to ssh to enforce pty]
[v3: disable events tests for cgroupv2]
[v4: update fedora packages, use a single dnf transation]

This adds targets for rootless integration tests, as well as all of the
required setup in order to get the tests to run. This includes quite a
few changes, because of a lot of assumptions about things running as
root within the bats scripts (which is not true when setting up rootless
containers).

This fixes all of the tests that were broken as part of the console
rewrite. This includes fixing the integration tests that used TTY
handling inside libcontainer, as well as the bats integration tests that
needed to be rewritten to use recvtty (as they rely on detached
containers that are running).
This patch is part of the console rewrite patchset.

This makes it much simpler to write tests, and you don't have to worry
about some of the oddness with bats.
