Subject: [PATCH] sage: rename python package from sagelib to sagemath

This change fixes `nix build .#sage`. The regression is due to a new check, pythonMetadataCheckHook,
introduced in #532778; the check enforces that pname matches the metadata name of the underlying Python
project being built, typically in pyproject.toml; in this case the underlying name is "sagemath".
