pm_test: Unset LD_LIBRARY_PATH, PYTHONPATH and PYTHONHOME to start system terminal

gnome-terminal is using a python3 starter script that has to load the system wide modules/library to work properly. That's not the case in pm_test is started from a checkbox snap where all those env var point to paths inside the snap. This patch unset them to ensure gnome-terminal (via x-terminal-emulator) starts with the right env. For the record the error was: ImportError: module encoding not found
