Install rust and cargo in manylinux image, prune unused packages. (#11)

Progress on nod-ai/shark-ai#679

Tested:
```bash
cd base-docker-images
sudo docker buildx build --file dockerfiles/manylinux_x86_64.Dockerfile . --tag manylinux:latest

cd ../shark-ai
CACHE_DIR=~/.shark-ai-cache \
  OUTPUT_DIR=/tmp/wheelhouse \
  MANYLINUX_DOCKER_IMAGE=manylinux:latest \
  sudo -E ./shortfin/build_tools/build_linux_package.sh

# ******************** BUILD COMPLETE ********************

# Generated binaries:

```

Note that this image is in use without pinning in some repositories, but
from what I can tell, all affected workflows are already failing and the
code is unmaintained. For example:
https://github.com/nod-ai/SRT/blob/373685f1cfff5dd6d934bf5858b6d58fc7a5bcdf/build_tools/pkgci/build_linux_packages.sh#L67.
