HP 820 G2: Use fam15h cbfstool tree for refcode

We used cbfstool from coreboot 4.13, because it was the
last version to work with the particular format used
for stage files, before the CBFS standard changed in newer
releases of cbfstool.

When I added this board to Libreboot, it was source-only at
first so it didn't matter. I didn't want to do a standalone
cbfstool binary, in case some people decided to use that one
on newer boards, which would cause all sorts of issues.

So I bodged it and just included an import of coreboot 4.13.

Well, the cbfstool from coreboot 4.11, as used for FAM15H
AMD boards, is compatible. I checked the code diff between
the two, and there is no meaningful difference.

I've tested this, and it works, since the last release or
two now includes 820 G2 images, so I  was able to use those
with ./mk inject, to verify whether the refcode file is
still grabbed properly. We need the refcode to handle MRC
on Broadwell platform, but we extract it from an old Google
Chromebook image, that uses the old CBFS stage file layout.

This change solves my problem: the problem was that releases
are bloated further, due to including this extra coreboot
version. This should reduce the size of the next release
considerably, especially after decompressing the tarball.

-Subject: [PATCH 1/1] Fix cbfstool build error on GCC 15 host compiler
-
-GCC 15 now considers the unterminated-string-initialization warning as
-part of -Werror by default. Coreboot compiles host utilities with the
-system compiler, which results in getting this error in some files.
-
-Mark a hexadecimal translation table in cbfstool code as "nonstring" to
-avoid the warning-turned-error.
