[GStreamer] Add missing <wtf/MathExtras.h> header
https://bugs.webkit.org/show_bug.cgi?id=133236

Patch by Adrian Perez de Castro <aperez@igalia.com> on 2014-05-27
Reviewed by Philippe Normand.

In some configurations, not including <wtf/MathExtras.h> will cause
errors about undefined functions. In particular, this happens in
Linux with glibc 2.19 and compiling with Clang. Having the header
included is the correct thing to do anyway.

* platform/graphics/gstreamer/GStreamerUtilities.cpp:
Include <wtf/MathExtras.h>
