Fix how mkarchiso makes usb image
The current implementation in how partition is created for ext2 img it looks a bit bad. This patch makes the partition in more standarized way, respecting cylinder alignement: * The size of resulting image will be in cylinder multiple ~8MB. * Use fdisk instead of sfdisk (sfdisk write some bad information) * Make the result image in one pass, instead of concatenating. Also the advantage is that with this can add another partitions without any issues in the usb-flash-drive with this .img.
