dd: avoid unnecessary memory copies
* src/dd.c (scanargs): When not otherwise required (e.g. for
conversion), use two-buffer mode only when the input and output
buffer sizes differ. Before, some of the most basic invocations of
dd, e.g., dd < in > out, would unnecessarily use separate buffers
and perform memory copies between them.
