build: use rust stable for linting

Nightly clippy is no longer required, so we can remove its
requirement and thus simplify the devel rather than require using both
stable and nightly compiler.
Nightly fmt is still required, but since the options we need are still not
stable, I think it's better to drop them for a more mainstream approach.
This should also reduce the target/debug size as there'll be only
builds from one compiler.
