[patch] kernel protocol learn on FreeBSD 7

[Eugene Perevyazko]

Hello bird-users readers!

I'm trying to use bird on PPP access-server running FreeBSD 7.

The first problem I've met was bird not learning routes that are added and
removed by ppp daemon based on Radius user-data.

I've made a simple patch but not sure if it is full and correct.
Can anyone review it? Especially I'm not sure what should be marked as 
KRT_SRC_REDIRECT and what are the consequences of not using this value.
