Enable building 0.24-fixes without system V4L1 support.

This patch retrieves videodev_myth.h from revision 6ff252d
(the revision before it was removed in bf7225c ), and
modifies the MythTV code to use it, instead of the system
linux/videodev.h header, so that MythTV will compile and work properly,
even on systems based on the Linux 2.6.38+ kernel headers.
