twister: terminate_process: fix NoSuchProcess error

Browse source 
NOTE: Even though previous commits indicate, that this can only happen on
MacOS, that's actually not true. It happens on Linux as well.

The constructor of `psutil.Process` can throw an exception as well, so we
need to wrap the whole loop in another try, unfortunately.
