third_party/linux: disable fallback tunnel devs

Introduces a patch for a kernel config option to control the default
behavior for fallback tunnel devices in the kernel.
We want to fully disable them but this can otherwise only be done by
passing kernel commandline arguments which would need to be specified in
a lot of places and can easily be missed.

This will get rid of things like the sit0 interface in the host and
container namespaces.
