commit 2a7d4e2840ec4d98de608d1ee3bf4a4ad9cc1b1d

build-system/pyproject: Avoid PEP427 substitution on binary files.
In some rare cases, the dest-path can be an elf-file, which are
unreadable by substitute*, leading to an error instead of just
continuing which makes more sense in this case.
* guix/build-system/pyproject.scm (check): Guard substitution attempt
with basic readability guarantees.
