Ensure that output and errors from the underlying build command are streamed for real-time build progress updates and debugging. This change strips out all code that is currently unecessary and adds tests for the remaining functionality. Test: atest --host build_test_suites_local_test build_test_suites_test Bug: 330365727 Change-Id: I7ef98d6654fe1435cf67c15e2c516a0967e03a75
