benchmark: change format of ts file to yaml

1. Use libyaml to generate timestamp dump file in YAML format.
2. Misc cosmetic changes and refactoring (debug output).

Example of ts file:
timestamps:
    - core: 0
      counter: 5818870656
      address: 0x804d01f0
      component: kmodule
    - core: 0
      counter: 5819087360
      address: 0xe01d81b
      component: core
...
