Align the partition end sectors and add partition names
sgdisk by default only aligns the partition start. Use the --align-end option to align the partition end too.
Additionally:
* Add PARTLABEL values to all partitions.
* Do not hardcode the partition number and end sectors in sgdisk commands by using the special value "0".
* Follow the Discoverable Partitions Specification by using the "Linux x86-64 root" partition type.
