perf test: Set PERF_EXEC_PATH for script execution
[ Upstream commit e4ef3ef1bc0a3d2535427da78b8095ef657eb474 ]
The task-analyzer.py script (actually every other scripts too) requires
PERF_EXEC_PATH env to find dependent libraries and scripts. For scripts
test to run correctly, it needs to set PERF_EXEC_PATH to the perf tool
source directory.
Instead of blindly update the env, let's check the directory structure
to make sure it points to the correct location.
