rootless: report correctly the error

`err` is nil at this point, so errors.Wrapf() would return nil
ignoring the remaining arguments.  This would prevent SetupRootless()
to fail causing podman to run without capabilities but believing so,
and it would end up in a crash when accessing the local store.

Closes: https://github.com/containers/podman/discussions/12923

[NO NEW TESTS NEEDED] it requires running in the environment created
by bazel linux-sandbox.
