rbd: add missing FileStream::get_size

At the moment, a few methods will be stubbed if
BOOST_ASIO_HAS_POSIX_STREAM_DESCRIPTOR is undefined.

The issue is that FileStream::get_size is undefined, so we're
getting link issues on Windows.

In the future, we might consider using asio::windows::stream_handle
on Windows.
