Aidegen: move code coverage report to temp folder

Coverage.py would generate some file in project folder. It would show
uncommited changes while uploading in asuite git.
This patch delete the .coverage file and move code coverage report
to temp folder.
And fix preupload test fail.

Bug: 122860949
Test: command: $ bash run_tests.sh
      1. Check there are no new files generated in project folder.
      2. Check the code coverage and the code coverage link should link to a code coverage analyze page.
