[PATCH v2 23/25] Removed unnecessary include.

[Alejandro Colomar]

Some OSes, as Linux, provide FIONBIO in <sys/ioctl.h>.  Others,
such as the BSDs and Illumos, provide it in <sys/filio.h>, but
they all include that header from <sys/ioctl.h>, so for this test,
we can simplify and just include <sys/ioctl.h>.
