[PATCH 2/7] rteval: Add --cleanup-cpusets flag to remove leftover cpusets

Add a new command-line flag --cleanup-cpusets that removes any
leftover rteval cpusets from previous runs and exits. This is useful
when rteval was killed and didn't clean up properly, or when users
want to manually clean up without starting a new rteval run.

The cleanup function already existed and runs automatically at
startup when using --cpusets, but this flag makes it available
as a standalone utility command.

Changes:
- rteval-cmd: Add --cleanup-cpusets argument and early handler
- rteval/cpusetmanager.py: Change log level to INFO for "no cpusets
  found" message so users get feedback when running --cleanup-cpusets

Example usage:
  sudo ./rteval-cmd --cleanup-cpusets
