trinity: undefined UIO_MAXIOV need sys/io.h

This patch fixes the build error produced by building
for powerpc 32bit after the glibc bump to 2.26
with the following internal toolchain config.

gcc5.4.0
glibc2.26
bin2.28.1
linux4.1.43

Failure log:
  CC	net/proto-ipv4.o
net/proto-ipv4.c: In function ‘ip_setsockopt’:
net/proto-ipv4.c:231:49: error: ‘UIO_MAXIOV’ undeclared (first use in this function); did you mean ‘_IO_MAGIC’?
   so->optlen = rnd() % sizeof(unsigned long)*(2*UIO_MAXIOV+512);
                                                 ^~~~~~~~~~
                                                 _IO_MAGIC

 Applied to master, thanks. However, I think the Sob of Vinson Lee was incorrect
here, I don't think he had anything to do with the Buildroot patch. And also:
