Subject: [PATCH 2/2] perf test: Set PERF_EXEC_PATH for script execution

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.

Fixes: e8478b84d6ba ("perf test: add new task-analyzer tests")
