Log:
  arm64: convert virtual machine images to GPT
  
  These images were switched to MBR in r281876 as a way to cope with a
  hard-coded partition GUID in QEMU's default EFI firmware. Enough time
  has passed that this is no longer a problem; QEMU versions >= 4.0
  include a copy of edk2 EFI firmware that can detect the root filesystem
  properly. Alternatively, sysutils/u-boot-qemu-arm64 can be used.
  
  Switch back to building these images with a GPT partition table, and
  re-enable the swap partition.
