winemac.drv: Actually make the GL context current even if no drawables were given. 

The spec for GL_ARB_framebuffer_object (and thus, OpenGL 3.x and up) is
quite clear on what happens when a context is made current with no
drawable(s). In fact, the WGL_ARB_create_context extension amends
WGL_ARB_make_current_read (as well as the base spec for wglMakeCurrent)
specifically to allow this.
