    staging: Fix sysroot problem with populate_sysroot dependencies on do_fetch
    
    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 a separate function before
    the extend_recipe_sysroot prefunc else we'd wipe out the sysroot we just created.
    
    This allows fetcher do_populate_sysroot dependencies to work correctly again.
    
    I did try various other approaches and a seperate function with cleandirs was the
    cleanest way to add this without code duplication or too much complexity.
