Use uint32_t instead of int to support 2~4G file

MtpDevice::sendObject is using int to define object size,
if the object size is bigger than 2GB, the size will be type-cast to
a negative number. And it will cause a endless loop in MtpDataPacket::write
until DUT auto reboot.

And JNI api android_mtp_MtpDevice_send_object requires that object
size must be uint32_t , so MtpDevice::sendObject works well after its
size parameter is changed from int to uint32_t.

Also change the return type of below API from int to int64_5
int64_t MtpDataPacket::write(struct usb_request *request, UrbPacketDivisionMode divisionMode,
        int fd, size_t size)
so that it can return the right size in the case of writing 2~4G file.

Test: manual - connect Android device to Android Automotive
Test: manual - select MTP/File Transfer in android device
Test: manual - copy a file which is bigger than 2GB from automotive to the android device.
