iptables: do not install /etc/ethertypes

Take inspiration from the ebtables recipe in meta-networking and omit
installation of etc/ethertypes, since it is provided by netbase. If we
don't do this, the following error occurs during build:

Error: Transaction test error:
  file /etc/ethertypes conflicts between attempted installs of
iptables-1.8.7-r0.core2_64 and netbase-1:6.3-r0.noarch

+Subject: [PATCH] Makefile.am: do not install /etc/ethertypes
+
+The /etc/ethertypes is provided by netbase since 6.0[1].
+Do not instal the file in ebtables, otherwise there would be a conflict:
+Error: Transaction test error:
+  file /etc/ethertypes conflicts between attempted installs of
+netbase-1:6.2-r0.corei7_64 and iptables-1.8.7-r0.corei7_64

+
+This patch is based off of the same change made for the ebtables recipe:
