Add a script to run "devtool modify" followed by a build on every target
recipe in the environment (with the option to skip/resume from/only
include specific recipes). This takes far too long to run as an
oe-selftest test but is still something that is useful to be able to
run. There's also a slightly quicker mode that just runs "devtool
extract" on each recipe.
