staging/image: Fix multilib recipe sysroot issues
Currently if you enable multilib, then build an image, the multilib
recipe sysroot is build in the wrong WORKDIR. If you then clean and
rebuild the image you see "file exists" errors.
This patch ensures the real WORKDIR is used consistently and then
cleans/rebuilds also work correctly.
