devtool: modify: make -x the default behaviour

It's going to be more common for users not to have the prepared source
tree for a recipe already, so the default behaviour ought to be to
extract it for them from the recipe. Change the default to extract
(effectively making the -x option a no-op) and add a --no-extract/-n
option to disable it. Later we can look at trying to be smart and
reusing an existing source tree instead of erroring out if it exists;
for now this is just the default reversal.
