ggsn: cmdline: no need to specify interface anymore
--gtpnl is now gone, instead you have --gtpkernel that behaves as an on/off
toggle. We full rely on the kernel routing base to select the real device to
transmit.
I have updated ggsn/cmdline.ggo and then run 'gengetopt' to refresh the
automatic code generation for command line options that openggsn uses.
