Add android.hardware.ethernet.xml for ranchu targets

This commit adds android.hardware.ethernet.xml file for ethernet
permission to PRODUCT_COPY_FILES which will be copied to
/system/etc/permission folder on the target. Reason for adding
this permission file is for enabling the ethernet and having
functional networking until RIL backend support in ranchu is

This requires dhcpcd_eth0 service definition in init.ranchu.rc.

Architectures that use goldfish emulator do not need ethernet
support, because networking is provided by RIL.
