cgpt: prioritize: Make sure all headers/entries are valid
The prioritize cmd expected primary gpt header and entries are valid.
Add a validity check to guarantee that.
BUG=b:35585016
TEST=Check on bob, the secondary gpt still valid after these commands:
dd if=/dev/zero of=/dev/mmcblk0 bs=512 count=64
cgpt prioritize /dev/mmcblk0
