Fix RISCOF timeout for arch-tests on macOS/Arm64

The SAIL reference model was timing out after 300 seconds (the default
RISCOF makeUtil timeout) when running >1000 tests sequentially on
macOS-arm64 GitHub runners.
- Add configurable timeout parameter to both SAIL and rv32emu plugins
- Set jobs=3 for parallel test execution (matches CI's -j3)
- Set timeout=900s for SAIL (slower reference model)
- Set timeout=600s for rv32emu (faster DUT)
