vttest-configure-c99.patch

I'm filing this under the C99 project, but it's a bug today, with current GCC. The configure script does not detect FIONREAD support because on GNU/Linux, it's defined in <sys/ioctl.h>:

“
checking for strerror... yes
checking if POSIX VDISABLE symbol should be used... yes
checking if we may use FIONREAD... no
configure: creating ./config.status
config.status: creating makefile
”

<https://kojipkgs.fedoraproject.org//packages/vttest/2.7.20220827/1.fc38/data/logs/x86_64/build.log>

I saw this because the test flags the implicit declaration of ioctl.

I assume this patch is okay, and I'm going to push it to rawhide.

(And I'm treating this as the de-facto upstream bug tracker. 8-)

Looks ok (I see that the check has been working for BSDs).
