IIRC, xfonts-unifont is pulled in by the unifont package on Debian, but
it is the one with the files you need. No, its not documented, but then
not every single debian package name needed is documented because the
documentation is partially distribution agnostic. If it were documented
it would be in ./INSTALL, which does talk about needing unifonts. If
you'd like to modify that file to help other Debian users, I'm
supportive.

These are very old, well known, and expected failures. I would love for
someone to fix them, but there's little interest. Daniel Axten looked
into fixing them a couple years ago, but looks like a pain[1]. I think
we should either only checksum the part of the image that doesn't
contain the version number, or generate the checksums in
grub-core/tests/checksums.h at build time.
