Broader error catching in Torch-TRT `userbenchmark` (#1974)
Summary:
- Failures on a [recent sample run](https://github.com/pytorch/benchmark/actions/runs/6436382237) indicate that errors raised by the subprocess are not always Exceptions, but are still sometimes recoverable
- Add `except` clause to catch all such errors, short of keyboard interrupts, so the compilation can complete despite such errors
