e2c79a1 started to blindly set the process name to the full path (instead of the basename) of the cmdline exectuable
if the process name from the process comm was truncated on linux. Python psutil never did that, and this is just wrong
for python (or any executable interpreted script) where the process name is not the interpreter binary but the script
itself.
A new test to check process name value against psutil value is added here, which would hopefully catch any potential
future changes in psutil.
