Fix VD svace problem.

 - The return type of fread is size_t has been converted to ssize_t.
 - At the previous implementation, because fread always returns positive value,
   the case ssize_t can be negative exists only when the fseek returns non-zero value.
 - This patch changes ReadBinFile to return false if it read nothing from binary.
