[PATCH 6/7] rteval: Update cpuset documentation to reflect simplified implementation

Update help text and docstrings to clarify that the simplified cpuset
implementation creates cpusets only for measurements and housekeeping,
not for loads. Loads use taskset for CPU affinity instead.

Changes:
- rteval-cmd: Update --cpusets help text to accurately describe that
  only measurement and housekeeping workloads get cpusets
- rteval/cpusetmanager.py: Update module docstring to clarify that
  loads use taskset rather than cpusets

This aligns the documentation with the simplified implementation
approach that mirrors isolcpus philosophy: measurements get isolation,
loads use affinity constraints.
