Need to add results check for rhel6.

The windows guest's time zone needs to be the same as host
before test.

-S will cause the guest system time is different with host system
 time when -rtc clock=vm.

1. fix config syntax error
2. increase the timeout for getting epoch time for windows guest
Signed-off-by: NSitong Liu <siliu@redhat.com>

Update:
    1. use epoch time to avoid timezone convert issue.
    2. use OS build-in shell to adjuest host/guest clock.
    3. use private brige to avoid guest sync time from network.
    4. remove s4 releated configuration.

This test will stop VMs for 1800 seconds, which will
trigger the inactivity watcher treshold, and print
messages such as:

    virt-tests-vm1 screen is inactive for more than 1802 s (30 min)

In this case the message is harmless, and more often than
not, will confuse users. Increase the inactivity treshold
for this particular test.
