[OE-core] [PATCH 10/14] devtool: reset: do clean for multiple recipes at once with -a

[Paul Eggleton]

We need to run the clean for all recipes that are being reset before we
start deleting things from the workspace; if we don't, recipes providing
dependencies may be missing when we come to clean a recipe later (since
we don't and couldn't practically reset them in dependency order). This
also improves performance since we have the startup startup time for the
clean just once rather than for every recipe.
