CI: remove separate check-build-tools-image workflow

[bayandin]

Problem

We call check-build-tools-image twice for each workflow whenever we use it, along with build-build-tools-image, once as a workflow itself, and the second time from build-build-tools-image. This is not necessary.

Summary of changes

• Inline check-build-tools-image into build-build-tools-image
• Remove separate check-build-tools-image workflow
