Add default RUSTUP_TOOLCHAIN for build step

As pointed out by harrysarsron on
https://github.com/starship/starship/issues/1805 and its linked issues,
users might not have a default rustup toolchain, or
even have a toolchain installed in their build environment.

Fix this by selecting RUSTUP_TOOLCHAIN=stable if there is not already a
RUSTUP_TOOLCHAIN selected by an environment variable.
