[libcxx-commits] [libcxx] [libcxx] Include python3-yaml and rsync in container (PR #194182)

[Aiden Grossman via libcxx-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/194182

rsync is needed for installing the kernel headers for the libc build. The yaml python package is needed for libc's hdrgen. This means we no longer have to install these utilities at runtime.

They should be small enough relative to the existing container image size to not really have an impact in that regard.

The yaml python package is needed for libc's hdrgen. This means we no
longer have to install these utilities at runtime.

They should be small enough relative to the existing container image
size to not really have an impact in that regard.
