rpi3: don't strip kernel8.img
In one of the final build stages, buildroot will strip [1] binaries by
running the following on all binaries under ./out-br/target:
$ aarch64-linux-gnu-strip --remove-section=.comment \
--remove-section=.note
When doing that on kernel8.img (which should be a 1:1 copy of
./linux/arch/arm64/boot/Image), the expected "magic" from the kernel
header disappears and so does a few other things as well. In short, the
kernel image becomes corrupt. Without the magic, U-boot won't pass
execution to Linux and will instead fail with the error message: "Bad
Linux ARM64 Image magic!"
To prevent kernel8.img from being stripped, we include it in the
BR2_STRIP_EXCLUDE_FILES Makefile parameter.
Why this suddenly started to show, I haven't been able to figure out.
