Christian Prochaska f8ba49f816 cpu_sampler_noux.run script
A run script to demonstrate the combination of the cpu_sampler, fs_log,
ram_fs and noux components for saving the sampled data in files and
accessing these in a Noux environment. When the script is run by the
autopilot, it will check if one of the generated sample data files
contains the correct instruction pointer. When the script is run
interactively, the generated files can be accessed from a Noux Bash shell.

Fixes #2078
