populate_sdk_ext: set noexec flag for some tasksChenQi/SDK-noexec
For the SDK, what we are interested in is the sysroot part. So the only useful task is do_populate_sysroot. Other tasks like do_package don't need to run. So mark them as 'noexec' for SDK. This would result in two benefits: 1) The size of extensible SDK is larged reduced. For example, extensible SDK for core-image-minimal is reduced from 1.8G to 793M. 2) The installation time is reduced as a lot of tasks are not run.
