image.bbclass: fix incomplete .rootfs customization

The patch for making the .rootfs configurable was incomplete: in the
python create_symlinks() method the new variable must be expanded
explicitly.

Not doing so broke the symlink creation and that led to hard build
failures in image types depending on the boot-directdisk.bbclass (like
qcow2) because the build_boot_dd() method relied on the symlink.
