include: can.h: add typedef for __kernel_sa_family_t to make headers self-contained

Browse Source 
This patch adds the typedef for __kernel_sa_family_t that was introduced in
Linux v3.1-rc2 (commit 6602a4b net: Make userland include of netlink.h more sane)
in <linux/socket.h>. It must be duplicated here to make the CAN headers
self-contained.
