[Branch-2.7][Build] Fix docker image install python3.7-dev problem

[gaoran10]

Motivation

Currently, when building docker image using branch-2.7, we met a problem, it seems that installing python3.7-dev in some os version need to add the apt repo ppa:deadsnakes/ppa.

Or maybe we could sync the DockerFile of the branch-2.7 with the branch master's to install the latest python3 component.
