Sounds reasonable, but - if there is only an issue with askpass and
everything else is fine, couldn't we just execute askpass from its
origin - instead of copying it to the destination ./git-test/
directory?

Friends, thank you so much for your kind help! Indeed: it turned out
that if /dev/shm is mounted with noexec then "--root=/dev/shm" is
failing. If you would like to ensure that the git tests are succeeding
regardless of what are the mount flags on some system or what some
distro's packagers are doing (more portability), maybe it is possible
to modify the git test system - to make it so that "askpass" always
gets launched from a native original directory, instead of being
copied to some "root" place where it could fail?

it would be possible to do that, but introduce a lot of complexity.
Right now test scripts are given a single temporary scratch directory
with a repo to do whatever they want with. If we gave each one _two_
directories, one for putting executable things and one for repo
operations, then the latter could be on a noexec filesystem.

But why do we want to support pointing --root to a noexec filesystem in
the first place? I think this falls into "if it hurts, don't do it".
