Subject: [PATCH] Optimize build pipeline

Commit [`e11f365`] introduced build time regression - the dockerfile was
modified to include two stages - one for build, another one for running.
However, our compilation pipeline uses cross to build binaries, then
copying it to final image. These dockerfile changes, combined with
existing building pipeline, caused to build the same binary four times:
two times for each supported platform.

This commit reverts changes back to original Dockerfile build process,
speeding up release pipeline (from ~1.5h to ~10 minutes).
