wireguard: do not add host-dependencies if fwmark is set

The 'fwmark' option is used to define routing traffic to
wireguard endpoints to go through specific routing tables.
In that case it doesn't make sense to setup routes for
host-dependencies in the 'main' table, so skip setting host
dependencies if 'fwmark' is set.
