gh-143309: fix `test_execve_env_concurrent_mutation_with_fspath_posix` buildbot failure

[picnixz]

It doesn't matter whether I spawn Python itself or another utility. I'm not sure if the issue with builbots is the fact that Python is installed as a shared library (and thus we're lacking some LD* variables in the spawned process) or if it's something else.

!buildbot "AMD64 Fedora"

!buildbot "AMD64 Fedora.*"

!buildbot "AMD64 Fedora Stable 3.x"

[bedevere-bot]

The regex '"AMD64 Fedora Stable 3.x"' did not match any buildbot builder. Is the requested builder in the list of stable builders?

This doesn't seem to work =/ I'm not sure if it's because of execve itself though.

If you want to schedule another build, you need to add the :hammer: test-with-buildbots label again.
