exclude static route with via ip in route helper (#1791)

Browse source 
When adding Routes to zerotier's Managed Routes, the helper will
add a route rule to the device that does not have a via ip,
so that the address of the Destination segment cannot be routed
correctly within the container.
Here, based on the contents of the routes key in
`zerotier-cli -j listnetworks`,
by determining whether the via key has an ip address,
if it is not null, helper will no longer add route rules.
