As mentioned on IRC, I don't think we overly need an extra check just
for this. Users have explicitly enabled zstd-compression that they
needed for their kernel (meaning they at least had zstd), and if it
somehow dies with "zstd: command not found" I think it's
self-explanatory.

Hard for it to be missing even if it's not in @system too given portage
currently depends on it. Not to say it couldn't, or change.
