rm_work: Improve handling for addto_recipe_sysroot

Rather than requiring each user to handle this individually, handle
addto_recipe_sysroot in the core class. As well as preserving the
sysroot directory, this also ensures the stamp is preserved rather
than rerunning the task every time as currently happens.
