fix v4l2 buffer ioctl fallbacks for pre-5.6 kernels
commit 2412638bb39eb799b2600393bbd71cca8ae96bb2 got the size of struct
v4l2_buffer wrong and omitted the tv_usec member slot from the offset
list, so the ioctl numbers never matched and fallback code path was
never taken. this caused the affected ioctls to fail with ENOTTY on
kernels not new enough to have the native time64 ioctls.
