bitbake: runqueue: Abstract the start and teardown worker functions
We're going to need a fakeroot/pseudo version of the worker so abstract the code to start the worker process. (Bitbake rev: b5d0f12f9df3ab211700473ed145ee6fbd9ca8e9) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
