gl-renderer: do not unbind the context on output destroy

Browse Source 
If we make EGL_NO_CONTEXT current, all following GL calls are
no-ops. This will be a problem when gl-renderer introduces
gl_renderer_color_transform containing GL textures and needs to destroy
them when weston_color_transform is destroyed. Mesa would print the the
warning that glDeleteTextures is no-op.

To fix this, keep our GL context current when destroying a GL output.

In case EGL_KHR_surfaceless_context is not available, we must use
dummy_surface.
