build-appliance-image: Load TUN at startup

This patch addresses the issue of not being able to execute "runqemu"
in the Build Appliance.
The root cause of the problem was that TAP/TUN was not available,
although required by "runqemu". In addition, the recommended remedy

  $ sudo modprobe tun

would fail for two reasons: modprobe not in PATH (user builder),
and "iptables" located in /usr/sbin but expected in /sbin.
