      `jdk.CPUInformation` event on AArch64 has valid CPU description in JDK-8262491, however it does not work on UEFI booted machine.

      JDK-8262491 refers device tree to get board name, however it does not exist on UEFI. We need to refer DMI.
      However we need to have root privilege, so we refer /sys/devices/virtual/dmi/id to avoid it.

      We can get board name from /sys/devices/virtual/dmi/id/board_name, but some machine set empty string to it. So we will refer /sys/devices/virtual/dmi/id/product_name as a fallback.
