uboot-sign: Refactor do_deploy prefunc to do_deploy_prepend

When inherited by the u-boot recipe (UBOOT_PN), uboot-sign.bbclass adds
a concat_dtb step, which places additional files into ${DEPLOYDIR}
before do_deploy. By turning this from a prefunc into a part of the normal
do_deploy function, it becomes possible to use
  do_deploy[cleandirs] = "${DEPLOYDIR}"
in the future, without deleting the files produced by concat_dtb.

As before, care is taken to not interfere with the kernel's do_deploy
definition, since concat_dtb was only needed for u-boot.
