sysmon: Remove unused venv run_tests

This run_tests isnt run in any *CQ.  Its replaced by the symlink
nonsense since those will get run automagically.

I had originally intended to get rid of this symlink nonsense, but I
have determined that it is better to coexist now.

The day will come when the virtualenv seeds sprout and drive out the
false symlink gods.  Oh yes, that day will come.

BUG=None
TEST=None
