shred: avoid a data pass on empty files
* src/shred.c (do_wipefd): Don't increase the size written
for an empty file up to a full block. Also increase the size
to OFF_T_MAX in the edge case where we do overflow.
* NEWS: Mention the shred improvements from recent changes.
* tests/misc/shred-passes.sh: Adjust as we no longer
write a BLKSIZE of data for empty files.
