km/common: simplify default environment
This is a first step to simplify the default environment. Move all the environment variables which are only needed for debugging purpose to textfiles in the scripts directory. In case of debugging these files can be loaded via tftp into RAM and set via the env import command. Other variables are identified as obsolete and were removed.
