sys-firmware/intel-microcode: bump

- Downgraded Microcodes:

  sig 0x000706a1, pf_mask 0x01, 2018-05-11, rev 0x0026 -> 2017-12-26, rev 0x0022

  "This MCU has been reverted to a previous version while Intel
  investigates a sighting related to this MCU. This error is currently
  under investigation and no workaround has been identified. Intel
  currently is recommending to stop deployment of version 0x26 and revert
  to the previous production version 0x22. Intel will provide an update on
  progress in 2 weeks." [Link 1]
