The problem came from Python libraries doesn't know the information that we enabled embedded_launcher (only Python binary knows about that). And we can't simply remove runfiles dir for Python libraries since host Python mode need this. Bug: b/80441699 Test: m perf_profo_flames Change-Id: I73ffc4d7504f95a708ae7cca47bc6c15a673aa31
