Bug description:
  [Impact]

  When running "lscpu" on a Grace-based system + Ubuntu 22.04, it
  doesn't report a model name:

  Vendor ID: ARM
  Model: 0

  [Fix]

  Adding the additional arm_part to sys-utils/lscpu-arm.c solves the
  problem. The commit below adds the specific codes missing from Jammy's
  version.

  https://github.com/util-linux/util-
  linux/commit/6857cccbb4157d5da34ca98f77a0ac9d68e1e740

  [Test Steps]

  * Verify whether output of lscpu is correct on new CPUs; eg:
  Vendor ID: ARM
  Model name: Neoverse-V2

  * Verify whether output of lscpu doesn't change on old CPUs; eg:
  Vendor ID: ARM
  Model name: Neoverse-N1

  [What Could Go Wrong]

  The fix only introduces additional model identifiers to match
  against and print a model name string, thus regression impact
  should be contained within lscpu and printing cpus model name
  on ARM systems. 

  Output doesn't change on systems with non-affected CPU models.
