Add rust compiler to base image builder

[brettlangdon]

What does this PR do?

Install rust compiler in the image builder stage.

Motivation

This will be needed in order to build dd-trace-py from source in the future

Testing Guidelines

I updated the pyproject.toml to point to a branch of dd-trace-py which needs a rust compiler.

I then ran the following command to build the image:

docker buildx build -t datadog-lambda-python-amd64 . --no-cache --build-arg "image=python:3.12" --bu
ild-arg "runtime=python3.12" --platform linux/amd64
