在有 Funfile 的情况下支持本地打包

目前是发现有 Funfile 就启用 docker。

```txt
using template: template.yml

start building function dependencies without docker

building xxx/xxx

Funfile exist, Fun will use container to build forcely
```

但是我们的 CI 上需要本地打包，开发时因为是 Mac 所以要使用容器进行打包。。

看了一下 build 的参数，并没有本地打包的选项

Start by reviewing the build parameters and the logic that enables Docker when a Funfile is present. Determine how local packaging can be selected without removing container-based packaging. Done means the build command supports both local and container packaging modes when a Funfile exists.
