There is already a (underdocumented) mechanism to copy binaries to the
barebox firmware directory: The PTXCONF_BAREBOX_FIRMWARE option and the
world/inject call.

Enable PTXCONF_BAREBOX_FIRMWARE and add the filenames of the binaries
that you want to install and their target location to the
BAREBOX_INJECT_FILES variable. The inject mechanism copies the files
from /usr/lib/firmware (BAREBOX_INJECT_PATH) to a specified location in
the barebox build directory.
