Register cleanup for antrea

Antrea fails to start after Windows nodes reboot because OVS bridge and
HnsNetwork previously created by Antrea is not cleaned, a cleanup script
is provided in the new version of Antrea, this change registers the
script as a callback on system's shutdown, the cleanup script will be
invoked before Windows shutdown.
