I'm still unclear on why this worked with all versions of macOS until
12, but the fix feels reasonable enough and I can't really justify
digging much further.

New subject: [libvirt PATCH 1/2] util: Preserve macOS dyld environment by default
The DYLD_* environment variables on macOS have the same purpose
as the LD_* variables have on Linux. Since we're preserving the
latter by default, it makes sense to do the same for the former
as well.

This is needed to ensure the environment variables that we need
for the test program itself, specifically to load mock libraries,
does not interfere with any command that gets invoked by it,
either directly or indirectly. We already perform the same
cleanup step for LD_* variables.
This makes the test failures
