Antonio Sanchez 852513e7a6 Disable testing of OpenGL by default.
The `OpenGLSupport` module contains mostly deprecated features, and the
test is highly GL context-dependent, relies on deprecated GLUT, and
requires a display.  Until the module is updated to support modern
OpenGL and the test to use newer windowing frameworks (e.g. GLFW)
it's probably best to disable the test by default.

The test can be enabled with `cmake -DEIGEN_TEST_OPENGL=ON`.

See #2053 for more details.
