zstd: fix crash when not overwriting existing files

This fixes the following crash:
  $ touch exists
  $ programs/zstd -r examples/ -o exists
  zstd: exists already exists; not overwritten
  Segmentation fault (core dumped)

* programs/fileio.c (FIO_compressMultipleFilenames):
Handle the case where we're not overwriting the destination.
