[Piglit] [PATCH 08/15] glean: call glewInit()

[Paul Berry]

Previously glean didn't initialize GLEW, presumably because glean only
uses GL 1.0 functions, and those functions bypass GLEW.  But once we
switch to using piglit-dispatch instead of GLEW, we will need to
initialize it in order for any GL functions to work.  This patch adds
a call to glewInit() in the place where a call to
piglit_dispatch_default_init() will eventually be needed.
