bpf-headers: fix use of netlink.h header

Browse Source 
netlink.h header have NL_SET_ERR_MSG_MOD that is tied to kmods. We don't
need kmods on bpf tools and this cause compilation error if the header
is included. Fix it by dropping NL_SET_ERR_MSG_MOD.

Subject: [PATCH] linux/netlink: drop NL_SET_ERR_MSG for kernel modules
We don't need NL_SET_ERR_MSG_MOD for bpf modules and we can drop it to
solve missing KBUILD_MODNAME define.

Subject: [PATCH] net/flow_offload: use NL_SET_ERR_MSG instead of
NL_SET_ERR_MSG_MOD
Use NL_SET_ERR_MSG instead of NL_SET_ERR_MSG_MOD for bpf modules as
kernel modules are not supported.
