A/B update: Replace the zip FileHeader mechanism for update package
When the update package gets larger than 2 GiB, payload.bin offset
mentioned in metadata file for ota-streaming-property-files gets
shifted (CrAU of payload.bin) because ZipInfo FileHeader() returns
incorrect value. To solve the issue, offset is re-calculated from
fixed bytes of central directory file header, filename length and
extra length.
Test: manually create an A/B update package and run it using
update_device.py
