android: camera_device: Fix exposure time tag in exif and android
The ExposureTime libcamera control is in microseconds while android and our exif component use nanoseconds. Convert it appropriately. CTS also expects the ExposureTime exif tag to match the ExposureTime set in the android result metadata. Fix it.
