test-reexec: Add script to address issues when task re-execution
The script is used to address build issues when tasks of different
recipes are re-executed. The script goes through all available recipes
and their tasks. The test results are saved in ./reexeclogs. Force build
logs are saved with prefix "force". Build failure logs are saved with
prefix "failed".
