mov: Fix negative size calculation in mov_read_default().
The previous code assumed if an atom was marked with a 64-bit
size extension, it actually had that data available. The new
code verfies there's enough data in the atom for this to be
done.
Failure to verify causes total_size > atom.size which will
result in negative size calculations later on.
