Thanks to the introduction of GPT partition table support in genimage,
this commit improves the pc_x86_64_efi_defconfig to remove the use of
the custom script creating the image.
Tested in QEMU, not on a physical device.
So:
- revert commit fee29b05bb7db25e37c8a5175ce00dc712554edf[1]
- add GPT support
- tweak shell script to add the correct UUID in genimage config.

Since all EFI-based systems support GPT, this commit changes
pc_x86_64_efi to use a GPT partition table. It shows an example of how
to craft a disk image with GPT partitioning instead of MBR. This is
achieved by means of a post-image script which uses
mkdosfs+mcopy+sfdisk, since genimage is unable to deal with GPT. Long
term, it would be ideal if genimage had GPT support, but until then,
this script shows how to achieve creating a GPT-based disk image.
The script was kept as simple as possible to make it easy to understand
and adapt for other purposes.
The root filesystem location is passed to the kernel by a partition
UUID, so it is possible to boot on QEMU, directly from the disk image,
or dump the image to a physical device.

Before this commit, the grub configuration file was copied to the
TARGET_DIR in a post-image hook, after the filesystem has been
generated. It was kinda working because the board/pc's grub
configuration and the default one are the same and the later was
copied during the build process of the grub2 package.
This commit ensures the custom board/pc grub configuration is copied at
the right time.
