hdd_menu.cpp: add support for sgdisk; fix sfdisk usage

- sfdisk is used primarily
- ensures detection of large hard drives
- using gpt tables with sfdisk or sgdisk

Note:
busybox fdisk doesn't support gpt tables and no large hard disks,
but fallback to old behavior should work unchanged
newer util versions of fdisk can do this but with different syntax.

Please test.
