Tool to fix the fs_size in the crypto footer

The GPT of HSPA Prime devices is incorrect when it comes from the factory.
Flashing a new bootloader fixes the GPT, but if the user had already
encrypted the device, the old size of the partition is recorded in the
crypto footer.  If the size if not updated, the device will not be able
to boot after the OTA, so add a new command to fix the fs_size field in
the crypto footer for Prime devices.
