I can copy the files into UBOOT_TRAVIS_BUILD_DIR as part of the job,
similar to what is being done for the grub*.efi files.

Should I mimic what is being done for the various grub.efi files? I
believe that these are in the /opt/grub/ directory of the docker
image, and get copied to the build dir at runtime.
