staging.bbclass: do not add extend_recipe_sysroot to prefuncs of prepare_recipe_sysroot

When running prepare_recipe_sysroot task, the extend_recipe_sysroot
is run twice.

What prepare_recipe_sysroot does is executing extend_recipe_sysroot,
there's no need to add extend_recipe_sysroot to its prefuncs.
