meta-lxatac-bsp: emmc-image: specify image for state/env even with fill:

This fixes failing builds caused by commit daccfdd ("meta-ptx: update
to current master with genimage v17"), which removed the image parameter
for the barebox state and environment partition in the assumption that
specifying the fill parameter instead would result in the partition
being zeroed out.

This is not correct. genimage still needs an image name for the partition,
but now it may have a length of zero because the rest of the partition
(e.g. everything) will be filled with zeros.

This fixes these genimage build errors:

  | INFO: cmd: "rm -rf "…/build/tmp/work/lxatac-oe-linux-gnueabi/emmc-image/1.0/genimage-tmp"/*" (stderr):
  | INFO: android-sparse(emmc-image-lxatac-2024…15.simg): input image: emmc-image-lxatac-2024…15.img
