[PATCH] dd: fix a printf format mismatch in an error message

[Pádraig Brady]

* src/dd.c (dd_copy): To print an off_t portably we need
to use PRIdMAX and cast to intmax_t, otherwise there
could be a mismatch between say a 32 bit off_t
and uintmax_t.  This was flagged by -Wformat on
a 64 bit host when compiling with CFLAGS=-m32.
