[PATCH] native: Use deltask to remove tasks which have no purpose

[Richard Purdie <richard.purdie@linuxfoundation.org>]

core-image-sato has 47703 inter task dependencies before this patch
and 29883 afterwards which is a significant worthwhile task graph
simplification.

Note: This patch depends on new bitbake functionality so we'll have to
bump the bitbake version requirement before we can do this.
