classes/image_types_fsl: Add support to use uboot extlinux

Class that allows extlinux.conf generation for U-Boot use was introduced
on OE-core commits:

  - 7c18abeb2a6ef8b7bb53aa92a9ee76bd465fada2
  - 33df3a65f3e8e136811da715d0cc247ce66ae0ea

We need to copy extlinux.conf file to boot partition inside /extlinux
directory. This file will be only copied if UBOOT_EXTLINUX is set to 1.
