[OE-core] [PATCH 3/3] staging: Fix sysroot problem with populate_sysroot dependencies on do_fetch

[Richard Purdie]

Dependencies on svn:// urls were failing as the cleandirs on do_fetch was destroying
any sysroot setup by the extend_recipe_sysroot function.

Add code so that if the task do_fetch, we move the cleandirs to the extend_recipe_sysroot
task else we'd wipe out the sysroot we just created.

This allows fetcher do_populate_sysroot dependencies to work correctly again.
