avicap32: fix build with recent kernel headers

[Rafał Mużyło]

Attached patch seems to fix build problem with recent kernel headers,
where v4l1 was removed. I'm sending it here first (instead straight
to wine-patches), as I have no real way of testing it - I only know it builds.

As such, I haven't bothered yet with keeping consistant folding style.

In case of any questions, CC me.

PS.: qcap *might* need a similar, though far more complex fix.
