[PATCH 12/15] tests: Update preadv test in order to reflect changed behaviour

[Eugene Syromyatnikov]

Since iovecs themselves are printed evan syscall has failed now, test is
updated to reflect this. It is notable, though, that this is the only
place where this case is checked.

* tests/preadv.c: Update output for the case when preadv with singe-item
iovec failed.
