config check for videodev.h

[Dustin Navea]

I don't think that would be appropriate, as systems that have sys/time.h
may not always have sys/types.h ..  I think probably

#ifdef HAVE_SYS_TYPES_H
#include <sys/types.h>
#endif

and of course you gotta have the lines to define HVE_SYS_TYPES_H

If you don't know autoconf very well, just look for where all of the
#defines are, and see how its checking for sys/time.h, and copy/paste
that for sys/types.h ..

Of course I could be going about this all wrong as I'm not one of the
developers.  Just my $0.02.
