Subject: [PATCH] Fix follow-up bug from the bindgen_env unbound-variable patch

The \${arr[@]:-} default-value form avoids bash 3.2's unbound-variable
error on an empty array, but on macOS's stock bash it still expands to
a single empty-string word, so `env "" cargo build ...` tried to exec
an empty command name and failed with exit 127. Build the cargo
invocation as an array and only wrap it with `env` when bindgen_env
actually has entries, avoiding any [@] expansion of an empty array.
