backend/drm: remove missing cursor plane workaround 

We have a workaround for legacy drivers that support drmModeSetCursor
without exposing a cursor plane. It doesn't work anymore now that we've
moved to a more atomic interface.

Let's just remove this workaround and fallback to software cursors.

Closes: https://github.com/swaywm/wlroots/issues/2166
