Add static route into cmdline if target address is not local

Browse Source 
If one target address is not local and its route is different than
default gateway, the specific route to this target address need be
added. E.g, target is 192.168.200.222.

sh> ip route show
default via 192.168.122.1 dev eth0  proto static  metric 1024
192.168.200.0/24 via 192.168.100.222 dev ens10  proto static  metric 1

In this patch, get the route to the specific target address and store
it as cmdline, here is /etc/cmdline.d/45-route-static.conf. And the
route options are separated by semicolon like below. Then the stored
route can be parsed when kdump kernel boot up.

192.168.200.0/24:192.168.100.222:ens10
