Python images need to support MUSL-based systems (alpine)

The `python:xx-alpine` images require Python debugger packages setup for musl. There doesn't seem to be any image metadata to identify musl/alpine-based images, so `skaffold debug` can't select a musl-specific image. So this seems to be something that has to be detected at runtime with the new python launcher.

Alpine images:
- /etc/os-release has ID=alpine
- /lib/ld-musl-x86_64.so.1
- /lib/libc.musl-x86_64.so.1
- /lib/libapk.so.3.12.0
- no /lib64

This [answer](https://unix.stackexchange.com/a/605854/65738) cites existence of /lib/ld-musl-* and /lib/libc.musl-*.

首先检查新的 Python 启动器，以及 `skaffold debug` 如何识别镜像。使用 issue 中列出的 Alpine 指示信息（例如 `/etc/os-release` 和 `/lib/ld-musl-*`）来定义运行时检测。完成标准是 Python Alpine 镜像可以接收 musl 专用的调试器设置，并能被 `skaffold debug` 选中。
