python310Packages.wasmer*: Fix build with maturin 0.14

With maturin 0.14.0 certain metadata fields cannot live in Cargo.toml
anymore. Instead of warning about it we're seeing a hard fail, so we
just go about and patch the names away, so it doesn't see them any
longer.

> The following metadata fields in `package.metadata.maturin` section
> of Cargo.toml are removed since maturin 0.14.0: classifier,
> project-url, please set them in pyproject.toml as PEP 621 specifies.
