canned-wks: use GPT partition table

According to UEFI specification all EFI platforms must support
GUID Partition Table(GPT) disk layout. Here is a list of advantages
of using GPT disk layout over the legacy MBR partitioning:

 - Logical Block Addresses (LBAs) are 64 bits (rather than 32 bits).
 - Supports many partitions (rather than just four primary partitions).
 - Provides both a primary and backup partition table for redundancy.
 - Uses version number and size fields for future expansion.
 - Uses CRC32 fields for improved data integrity.
 - Defines a GUID for uniquely identifying each partition.
 - Uses a GUID and attributes to define partition content type.
 - Each partition contains a 36 character human readable name.

Used GPT partitioning in all EFI kickstart files.
Tested result images on NUC, MinnowBoard MAX and MinnowBoard Turbot.
