Apply the timeout configuration of nm-initrd-generator

Browse Source 
nm-wait-online-initrd.service installed by dracut's 35-networkmanager
module calls nm-online with "-s" which means it returns immediately when
NetworkManager logs "startup complete" after certain timeouts are
reached. "startup complete" doesn't necessarily network connectivity has
been established. nm-initrd-generator has a set of timeouts that in most
of cases when applied, "startup-complete" means network connectivity has
been established. So apply it when setting up kdump network.
