Get object size that is more than 4GB.
MtpObjectInfo contains object size as 32-bit integer and the provider
needs to invoke MtpDevice#getObjectSizeLong hidden API to get 64-bit
object size.
The CL switches to use MtpDevice#getObjectSizeLong hidden API if
MtpObjectInfo#getCompressedSize() returns 0xffffffffL, which means the
object size is more than 4GB.
