nix: Fix (potential) glibc errors in dev shell (#17974)

Previously the rustc and cargo did were not declared dependencies
supplied to devshell. This means that shell relied some impure cargo and
rustc version found in the system. This lead to issues with GLIBC
version on systems which have different GLIBC version globally.

This package exposes nixpkgs rustc and cargo version into the shell
preventing issues with incompatibility.
