vboot: cgpt: fix my_lba of the secondary GPT

Browse Source 
Previously, my_lba of the secondary GPT was recorded as if that
GPT was written at the end of the device. This patch tweaks
my_lba to report where it is in the random-access GPT address space,
namely at the end of that space.

TEST=Compiled it into the firmware and observed the firmware to update
the my_lba field of the secondary GPT.
