    lib/oe/image.py: fix working directory

    The working directory needs to be changed before the image creation
    commands instead of afterwards.

exposed an issue when generating tar images, where it would cd into
rootfs and then create the rootfs tarball and remain there since the
cmd to cd into deploy dir moved up the immediate following cmd like
tar.bz2 or tar.gz were still looking for tarball in current directory
which esentially was not deploy dir but IMAGE_ROOTFS instead
