media: v4l2-compat-ioctl32.c: add capabilities field to, v4l2_input32

commit 037e0865c2ecbaa4558feba239ece08d7e457ec0 upstream.

The v4l2_input32 struct wasn't updated when this field was added.
It didn't cause a failure in the compat code, but it is better to
keep it in sync with v4l2_input to avoid confusion.
