install-scripts: initial support of GPT
Added a new parameter to choose between partition table type: GPT (GUID Partition Table) or MBR (Master Boot Record).
The default partition table type remains MBR for SECO i.MX6/8 boards, and GPT can be activated by passing a "--partition-table-type=gpt" parameter to fngsystem-self-init.sh script.
