utils/isohybrid.c: Correct end block address of first GPT partition
The GPT partition 1 covers the whole ISO filesystem size. GPT specs
demand that the partition end block number shall be the last valid
block in the partition. isohybrid.c rather wrote the number of the
first block after the partition end.
This change reduces the number by 1.
