Fix article generator producing 1xINTEL in GPU segment

MB_ lots (e.g. MB_INTEL_..._GPU8) are incorrectly categorized as GPU
in the pricelist. Two fixes:
- Skip MB_ lots in buildGPUSegment regardless of pricelist category
- Add INTEL to vendor token skip list in parseGPUModel (was missing,
  unlike AMD/NV/NVIDIA which were already skipped)
