Double functional testing timeout to 120s

[Dong Jun]

I encountered a similar problem to https://review.openstack.org/#/c/172148/

When i am dealing with the following question https://bugs.launchpad.net/networking-ovn/+bug/1670663,
increased testing time of ACL checking caused job failure due to TimeoutException in TestOvnNbSync.test_ovn_nb_sync_mode_log.

This is the log info, then i change the timeout time to 120, it's passing.
