[enh] container: compact venv (#5225)
We can leverage the immutable nature of containers to add additional
optimizations.

No debugging or tinkering inside containers, so stripping all unused symbols
inside `venv` should be fine. We are also going to compile the bytecode
ourselves to modify some parameters related to reproducibility.

With these small changes, we have reduced the `venv` layer size by 10MB~
