Revert "lib/oe/image.py: fix working directory"

This reverts commit 3f49597225.

This change appears to cause more problems than it fixes since the
compression commands usually work in the deploy dir but the archive ones
have always worked in the rootfs dir (which is clear from the tar command
we use).
