Add e2e tests for systemd's event-driven activation mechanisms and the
sd_notify watchdog protocol:
- TestSystemdTimer: transient timer units fire repeatedly on both the
monotonic (OnActiveSec/OnUnitActiveSec) and the realtime (OnCalendar)
clocks.
- TestSystemdDBusActivation: a bus call to org.freedesktop.hostname1
starts systemd-hostnamed on demand.
- TestSystemdSocketActivation: with only ssh.socket started, the first
connection starts ssh.service, which serves it on the inherited
listening socket.
- TestSystemdWatchdog: a Type=notify service with WatchdogSec= stays up
while it pings the watchdog, and is killed with Result=watchdog once
the pings stop.
All TestSystemd* tests now run in parallel, each in its own container.
The systemd entry on the website's compatibility page is also updated.

Without this, tests that `exec` commands into existing GPU containers (e.g.
the CUDA samples test) would not actually get ioctl compatibility
enforcement.
Updates issue #10885.

This allows tests to consider the exit code of `exec`'d processes.
This is useful for CUDA tests because they exit with a specific error code
(`EXIT_WAIVED`) when they run on GPUs that don't support the features the
test needs.

proctor is running in a sandbox and it executes tests. If it is able to
handle timeouts, we will know that a test sandbox is alive and proctor
will send SIGTERM to test processes and collect all logs.
In addition, these changes contains a few things:
* upload runsc logs with other test artifacts.
* increase log level for java tests.
* call Fatalf instead of Errorf when we want to terminate a test.

Previously, ICMP destination unreachable datagrams were ignored by TCP
endpoints. This caused connect to hang when an intermediate router
couldn't find a route to the host.
This manifested as a Kokoro error when Docker IPv6 was enabled. The Ruby
image test would try to install the sinatra gem and hang indefinitely
attempting to use an IPv6 address.
Fixes#3079.
