Subject: cleanup-workdir: only deal dirs related to current arch

Some users may build for different archs under same workdir, so they
don't want to clean the dirs not related to current arch.

Run command 'bitbake -e' with selected packages to get the dirs related
to current arch then clean them.

Update the way to get the WORKDIR by parsing the IMAGE_ROOTFS by the
way.
