openvswitch: add missing depends on coreutils-native
openvswitch: add missing depends on coreutils-native

I was getting the following error when building the latest master:

  ../git/build-aux/calculate-schema-cksum: cksum: not found
  ../git/build-aux/calculate-schema-cksum: cksum: not found

Adding coreutils-native which supplies 'cksum' resolved this.
