recipetool: create: support creating standalone native/nativesdk recipes

If the recipe name ends with -native then we should inherit native;
likewise if it starts with nativesdk- then inherit nativesdk.

(Note that the recipe name must actually be specified by the user in
order to trigger this - we won't do it based on any name auto-detected
from e.g. the tarball name.)

Since we're doing this based on the name, "devtool add" will also gain
this functionality automatically.
