wendelin: custom test runner to load our own libstdc++

Now the test runners use the LD_PRELOAD environment variable to load
the correct libstdc++ built by slapos and restart themselves.

The restart is necesasry because LD_PRELOAD is only taken into account
at the time the process is started. Changing this environment variable
in runtime has no effects.
