rslovers 9821737d06 vo_drm: fallback to vo_wait_default if VT switcher is not available 
When the drm video output is used under VT with a terminal multiplexer
like screen, the VT_SETMODE ioctl call will fail since the controlling
terminal is a pseudoterminal instead of a real one, thus the VT switcher
will be unavailable.

The problem is, the wait_events function inside vo_drm.c will test for
this, and will do nothing if the switcher is not active. Normally, this
would not be noticed, however, when you pause a video, or if you're playing
multiple image files, mpv will suddenly start busy waiting on a single
core.

I confirmed this by building mpv with gprof support, in a few seconds,
wait_events got called about 90 million times.

So I added a fallback, when the VT switcher is not availble, just use the
vo_wait_default function. I tested it and it's working well so far.
