Ubuntu 18.04 will reach its End of Standard Support in April 2023:
https://wiki.ubuntu.com/Releases
By updating Ubuntu from 18.04 to 20.04, the dynamically-linked glibc
version is bumped up from 2.27 to 2.31.
The dynamically linked containerd binary still seems to be compatible with
CentOS 7 (glibc 2.17).
The runc binary in the `cri-containerd(-cni)-<VERSION>-linux-<ARCH>.tar.gz`
bundle no longer works on CentOS 7, though, but this is acceptable, as the
`cri-containerd(-cni)` bundle has been deprecated since containerd 1.6.

The .github/workflows/release/Dockerfile will use working dir as docker
build context. But the .dockerignore will ignore the .github/release/...
and cause dirty. We should remove it and verify git working tree after
build.

This moves all the release builds into a Dockerfile which is a bit
cleaner for setting up our build environment.
Non-linux/amd64 builds are cross-compiled.
Currently onlinux linux/amd64, linux/arm64, and windows/amd64 are
supported, but is easy to add more, provided their is a cross-compile
toolchain available for it.
