static routes and 'src' parameter

[Saku Ytti]

Pilot error, this works:

filter kernel_out {
  if net = 0.0.0.0/0 then {
    #krt_prefsrc from lo;
    krt_prefsrc = 129.250.15.29;
    accept;
  }
  reject;
}

I wish 'krt_prefsrc from lo' would work, as it would require less
tooling to generate config :>. But no biggy. Thanks people!
