Subject: Add unix_diag.h to kernel userspace headers

From: Stephen Hemminger <[email-masked]>

The change to use provide unix domain diag information in iproute2 means that
an additional header file has to be added to the kbuild header export list.
This ensures that any changes to the header file get picked up in future merges.
