    openvswitch: add ct_clear action

    This adds a ct_clear action for clearing conntrack state. ct_clear is
    currently implemented in OVS userspace, but is not backed by an action
    in the kernel datapath. This is useful for flows that may modify a
    packet tuple after a ct lookup has already occurred.

Notes:
   - hunk from include/uapi/linux/openvswitch.h is missing because it
     was added with userspace support in 1fe178d251c8 ("dpif: Add support
     for OVS_ACTION_ATTR_CT_CLEAR")
   - if IP_CT_UNTRACKED is not available use 0 as other nf_ct_set()
     calls do. Since we're setting ct to NULL this is okay.
