  1. KSMController.is_ksm_running: Strip the output to avoid failure 

    The output of `process.run("cat /sys/kernel/mm/ksm/run").stdout_text`
is '0\n', which does not match numeric only string, the make the
function always returns `True`.

  1. KSMConfig.cleanup: Ensure ksm to be disabled at the end of the case 

    In the `cleanup` function, "start_ksmtuned" will start the
ksmtuned.service, it controls and tunes the ksm service, but depends on
the KSM_MONITOR_INTERVAL. So ksm is not closed immediately, but at some
time in KSM_MONITOR_INTERVAL loop. Without this fix, the next test case
may launch the guest with ksm enabled, which is not expected.
