[OE-core] [PATCH 3/5] devtool: extract: refactor kern-tools-native handling

[Paul Eggleton]

When extracting linux-yocto kernel source, we don't need to dance around
shutting down and starting up tinfoil anymore, we can just execute the
tasks as needed. This allows us to tidy up the code structure a bit.
