[shortfin] Upgrade package build dockerfile to manylinux_2_28. (#627)

Progress on #130.

The manylinux2014 image includes gcc 10.2.1 by default while
manylinux_2_28 includes gcc 12.2.1. At one point we had warnings/errors
building on the newer gcc version, but that is no longer the case.

With the new Rust dependency coming from
#610, we will likely want to
revive
https://github.com/nod-ai/base-docker-images/blob/main/dockerfiles/manylinux_x86_64.Dockerfile,
add more dependencies there, then switch from the upstream `quay.io/...`
image to that `ghcr.io/nod-ai/...` image.

Tested locally with `OUTPUT_DIR="/tmp/wheelhouse" sudo -E
./build_tools/build_linux_package.sh`. If the nightly package build
fails for some reason we can easily revert this.
