Use fshut() to properly flush the output stream

For small images, it could happen that the output stream would not be
flushed before exit(), resulting in a lack of error-reporting on
a full device. Using fflush(), a function I first introduced in sbase,
we do the flushing before returning manually and report errors if they
occurred.
