Jack Mitchell bc66b2f45a iptables: add systemd helper unit to load/restore rules
There is currently no way to automatically load iptables rules in OE.
Add a systemd unit file to automatically load rules on network
connection. This is cribbed from the way ArchLinux handles iptables with
some minor modifications for OE.
New rules can be generated directly on the target using:
# iptables-save -f /etc/iptables/iptables.rules
Good documentation for writing rules offline is lacking, but the basics
are explained here:

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
