openvswitch: bump to version 2.8.2

Changes since 2.8.2 as recorded in NEWS-2.8.2

    - NSH implementation now conforms to latest draft (draft-ietf-sfc-nsh-28).
    - Bug fixes

0006-adapt-ovs-scripts.patch was splited into two separate patches as
the original patch does not apply against 2.8.2 anymore.  Other patches
are just re-numbered without actual function change
