use build-script for static linux sdk build

[xavgru12]

Motivation

As of now the static linux sdk is built with this build.sh:

https://github.com/swiftlang/swift-docker/blob/main/swift-ci/sdks/static-linux/scripts/build.sh

Why is this separate from the common build? Why is this inside a docker repo when it is unrelated to docker?

Proposed solution

The main goal of build-script is to give a unified and reproducible build experience for everyone.
Providing a build.sh like this is not in favor of this.

Solution:
Integrate the linux static sdk build into the build-script.

What do you think? @MaxDesiatov

I don't think this is a good idea. @etcwilde and @edymtt are currently busy building an entirely new build system and I think integrating the static SDK build into build-script at this point would not make sense.
