net: Remove CONFIG_KMOD from net/ (towards removing CONFIG_KMOD entirely) 

Some code here depends on CONFIG_KMOD to not try to load
protocol modules or similar, replace by CONFIG_MODULES
where more than just request_module depends on CONFIG_KMOD
and and also use try_then_request_module in ebtables.
