libhwjpeg: Add backwards compatibility with older camera blobs

Based on:
https://github.com/LineageOS/android_hardware_samsung_slsi-linaro_exynos/commit/2fe7c2f00c90990b5e54b380912cca834d643ee1
https://github.com/LineageOS/android_hardware_samsung_slsi-linaro_exynos/commit/609cb39b6ecb0fc54ee2fe3c658f0c248eefd0d7
except, while two paddings are added there in exif_attribute_t (asides
from the one that has turned out to just be an extension of the model
member), there actually only appears to be a new offset_time member
here.

All appears okay with Android 9 and 11 camera blobs, with corresponding
BOARD_HWJPEG_ANDROID_VERSION settings.
