  Log Message:
  -----------
  ovs-bugtool: Fix crash when enable --ovs.

When enabling '--ovs' or when not using '-y', ovs-bugtool crashes due to
Traceback (most recent call last):
  File "/usr/local/sbin/ovs-bugtool", line 1410, in <module>
    sys.exit(main())
  File "/usr/local/sbin/ovs-bugtool", line 690, in main
    for (k, v) in data.items():
RuntimeError: dictionary changed size during iteration

The patch fixes it by making a copy of the key and value.
