backend/drm: Fix hardware cursors when rendering to linear is not available

Browse source 
GPUs such as NVIDIA and VmWare do not support rendering to a linear
buffer, but require linear cursor buffers. This means we have to
render to some other format, and then convert it ourselves.

This change advertises any render format as an available cursor format.
