When the sandbox runs in attached more, e.g. runsc do, runsc run, the
sandbox lifetime is controlled by the parent process. This wasn't working
in all cases because PR_GET_PDEATHSIG doesn't propagate through execve
when the process changes uid/gid. So it was getting dropped when the
sandbox execve's to change to user nobody.

container.startContainers() cannot be called twice in a test
(e.g. TestMultiContainerLoadSandbox) because the cleanup
function deletes the rootDir, together with information from
all other containers that may exist.

Adds two tests. One to make sure that $HOME is set when starting a container
via 'docker run' and one to make sure that $HOME is set for each container in a
multi-container sandbox.

- Sandbox logs are generated when running tests
- Kokoro uploads the sandbox logs
- Supports multiple parallel runs
- Revive script to install locally built runsc with docker

A recent Kokoro change pointed to go_tests.cfg (in line with the
other configurations), which unfortunately broke the presubmits.
This change also enabled the KVM tests, which were still using a
remote execution strategy.
This fixes both of these issues and allows presubmits to pass.
One additional test was caught with this case, which seems to
have been broken. It's unclear why this was not being caught.

This is done because the root container for CRI is the infrastructure (pause)
container and always gets a low oom_score_adj. We do this to ensure that only
the oom_score_adj of user containers is used to calculated the sandbox
oom_score_adj.
Implemented in runsc rather than the containerd shim as it's a bit cleaner to
implement here (in the shim it would require overwriting the oomScoreAdj and
re-writing out the config.json again). This processing is Kubernetes(CRI)
specific but we are currently only supporting CRI for multi-container support
anyway.

The simple test script has gotten out of control. Shard this script into
different pieces and attempt to impose order on overall test structure. This
change helps lay some of the foundations for future improvements.
* The runsc/test directories are moved into just test/.
* The runsc/test/testutil package is split into logical pieces.
* The scripts/ directory contains new top-level targets.
* Each test is now responsible for building targets it requires.
* The install functionality is moved into `runsc` itself for simplicity.
* The existing kokoro run_tests.sh file now just calls all (can be split).
After this change is merged, I will create multiple distinct workflows for
Kokoro, one for each of the scripts currently targeted by `run_tests.sh` today,
which should dramatically reduce the time-to-run for the Kokoro tests, and
provides a better foundation for further improvements to the infrastructure.
