Fix flaky integration_tests/scheduler/test_generic_driver.py

[xjules]

Apparently these test fail sometimes:

FAILED integration_tests/scheduler/test_generic_driver.py::test_submit_something_that_fails[LsfDriver] - assert 0 == 42
FAILED integration_tests/scheduler/test_generic_driver.py::test_kill[LsfDriver] - assert 0 in [143, 130, 265, 271]
