cmd: gpt: solve issue for swap and rename command

Browse Source 
don't use prettyprint_part_size() in create_gpt_partitions_list()
that avoid to align offset and size to 1 MiB and increase precision for
start and size.
This patch avoid the risk to change partition size and lost data during
rename or swap.
