Fix a warning about ‘sincos’ in examples/cogl-gles2-gears
‘sincos’ is a GNU extension. cogl-gles2-gears was using it without
defining _GNU_SOURCE so it was generating some annoying warnings. This
patch fixes it by making the example include config.h which will end
up defining _GNU_SOURCE.
In addition this patch adds a configure check for the function and
provides a fallback if it's not available.
