cleanup: address pylint "consider-using-with" in tracevol.py

Browse Source 
pylint started to report errors like the following:

    troubleshooting/tools/tracevol.py:97:10: R1732: Consider using 'with' for resource-allocating operations (consider-using-with)

There probably has been an update of Pylint in the test-container that
is more strict than previous versions.
