fix/ci: limit parallize build
Created by: leandro-arm
This patch limits parallize build features in order to reduce memory footprint and CPU resources needed to run this test. It also reduces the number of simultaneous builds performed. It only builds one product at a time.
Piped stdout stream is removed and stderr stream is directly printed instead of being piped, this reduces the memory footprint.
