efi_loader: PARTITION_UUIDS should be optional
In the current implementation, partition table support (either GPT or DOS)
is not mandatory. So CONFIG_PARTITION_UUIDS should not be enabled
(selected) unconditionally.
Fixes: commit 17f8cda505e3 ("efi_loader: set partition GUID in device path for SIG_TYPE_GUID")
