random aside, but we're not super consistent here, some of these have an
additional ' ' space.

I guess a next step would be a drm_fdinfo_printf(drm_printer *p, const
char *name, const char *printf, ...) and maybe some specialized ones that
dtrt for specific parameters, like drm_fdinfo_llu().

But that's for next one I guess :-)
