x32: fix decoding of flags argument of preadv2 and pwritev2 syscalls

x32 is the only linux architecture where preadv2 and pwritev2 syscalls
take 5 arguments instead of 6.

* io.c (PREADV2_PWRITEV2_FLAGS_ARG_NO): New macro.
(SYS_FUNC(preadv2), SYS_FUNC(pwritev2)): Use it.
* linux/x32/syscallent.h (preadv2, pwritev2): Change nargs to 5.
* NEWS: Mention this fix.
* tests/preadv2-pwritev2.c (main): Fix invocation of preadv2
and pwritev2 syscalls on x32.
