part: detect EFI system partition
Up to now for MBR and GPT partitions the info field 'bootable' was set to 1
if either the partition was an EFI system partition or the bootable flag
was set.
Turn info field 'bootable' into a bit mask with separate bits for bootable
and EFI system partition.
This will allow us to identify the EFI system partition in the UEFI
sub-system.
