Skip slow camera test and use run_subprocess() for eval_runner tests (#596)

## Summary
CI subprocess tests are slow and faced with timeout without stalling

## Detailed description
- Skipped `test_eval_runner_enable_cameras` as cold-start camera
rendering takes ~1165s, making CI exceeding the timeout.
- Replaced raw `subprocess.run()` with the shared `run_subprocess()`
helper, which enforces `ISAACLAB_ARENA_SUBPROCESS_TIMEOUT` (900s in CI).
- Removed redundant stdout-regex failure check; the eval_runner already
exits non-zero on job failure (no` --continue_on_error`).
