Subject: [PATCH] iverilog: 12.0 -> 13.0

- Update version to 13.0.
- Update source hash and tag format.
- Remove 'format-security' patch as it is included upstream in 13.0.
- Enhance installCheckPhase to handle regression tests more robustly:
    - Add build directories to PATH to ensure local binaries are tested.
    - Use -B and -M flags for Perl test suites to prevent stderr pollution
      from breaking gold file comparisons.
    - Unset IVERILOG_ICONFIG and IVL_ROOT for Python tests to maintain
      a clean test environment and avoid driver warnings.
