On certain Ubuntu systems running the 4.4 based kernel depmod

openvswitch kernel modules have been installed in the extra

When this occurs the 'make check-kmod' command will experience many
failures and openvswitch will not operate correctly.
Adding 'search extra' to the beginning of the /etc/depmod.d/openvswitch.conf
module dependency configuration file fixes the problem. So to be safe
just add it.
