When building an image including iptable built with the libnftnl
PACKAGECONFIG, one hits

Downloading file:.../oe-rootfs-repo/armv8a/libkmod2 * check_data_file_clashes: Package iptables wants to install file .../rootfs/etc/ethertypes
        But that file is already provided by package  * netbase

This used to be handled by
0003-Makefile.am-do-not-install-etc-ethertypes.patch, but that patch
got removed with the 1.8.9->1.8.10 upgrade (commit 4616ada82e70).

I think the rationale for dropping the patch was wrong; the commit log
talks about xtables.conf, which is indeed gone from upstream, but said
patch didn't change anything about xtables.conf, it did

-dist_conf_DATA        = etc/ethertypes etc/xtables.conf
+dist_conf_DATA        = etc/xtables.conf

However, instead of patching iptables to not install ethertypes, and
having to forward-port that patch, it is much simpler to just remove
the file in this do_install:append.

Hello,

this is a trivial cherry-pick of commit 3b9c8d5c26a4 ("iptables: remove
/etc/ethertypes"). This fixes building Scarthgap with

	PACKAGECONFIG:append:pn-iptables = " libnftnl"
	CORE_IMAGE_EXTRA_INSTALL = "netbase iptables"

.

Best regards
Uwe
