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
