shred: port to GNU/Linux behavior with tape drives

See: http://bugs.gnu.org/17149
* src/shred.c [__linux__]: Include <sys/mtio.h>.
(dorewind): New function, which works around the lseek problem with
tape drives on GNU/Linux, the same way that dd does.
(dopass): Use it.  New arg ST, needed for dorewind.  All uses changed.
(do_wipefd): Don't rely on undefined behavior on integer overflow
of file sizes.  Use INT_ADD_OVERFLOW instead.
