vo_drm: nake drm mode help output also output refresh rate 

The printout of available modes that you can get with --drm-mode=-1
(with -vo drm or --opengl-backend=drm) does not include the refresh
rate in the printout, which is quite useful to know, if one is to
choose for instance 23.98, or 24 Hz for film material.
