Avi Kivity d170efbfcb fstream: optimize file_data_source_impl ...

file_data_source_impl always calls file::size(), which can be slow.  This
slows down applications that create many short-lived input streams on the
same file (for random-access processing of a subset of the data).

Fix by not calling size(), and letting the file code handle short reads
itself.
