[PATCH 1/1] linux-kernel: add cleandirs flag for tasks

[Christoph Steiger]

Provide a cleandirs flag for directories that are used and expected to
be empty during do_dpkg_source and do_prepare_build. This is the proper
way to make sure directories exist and are empty.

This also allows users to extend e.g. the do_dpkg_source functionality
since that otherwise depends on the prepend order.
