tests/functional/gl_basic: Add tests for glx

Add tests:
    gl_basic.glx_gl
    gl_basic.glx_gles1
    gl_basic.glx_gles2

The gl tests does basic rendering. The gles tests check that waffle_init()
returns an error, because Mesa's GLX does not yet implement the GLX
extension needed to create ES contexts.
