egl: Add a note explaining the swapBuffers badness in dri2_x11_copy_buffers().

I tried to drop the swapBuffers path, but it turns out it's being taken by
softpipe/llvmpipe, and the tests are passing.  The piglit egl-copy-buffers
test even passes on zink, but you end up with a bad display because of an
un-preserved back buffer.
