postfix: split /etc from ${PN} to ${PN}-cfg for ostree

Browse Source 
In postinst of ${PN}, call newaliases on etc may fail at do_rootfs
due to host setup. If fail, the postinst will rerun at target first
boot which cause update-alternatives in postinst rerun.

For ostree system, /usr is readonly, /etc is writable, the
update-alternatives will be failed when run on target since it
needs write files in /usr. Split the postinst into two packages
can fix the problem:
* update-alternatives runs at do_rootfs
* newaliases runs at do_rootfs or first boot, it needs write files
  in /etc when run at first boot, while /etc is writable for ostree.

For non-ostree, everything will be OK as normal
