Make sure we can install podman even when the podman-mac-helper install
command fails. This used to be the behavior but commit bae07b6ea2 caused
the regression because the binary now returns 1 as exit code on errors.
[NO NEW TESTS NEEDED] I am not sure if we can test the install step in
CI.
Fixes#17910
