lavf/dv: do not set video timebase more than once

Browse Source 
Current code will call avpriv_set_pts_info() for each video frame,
possibly setting a different timebase if the stream framerate changes.
This violates API conventions, as the timebase is supposed to stay
constant after stream creation.

Change the demuxer to set a single timebase that is fine enough to
handle all supported DV framerates.

The seek tests change slightly because the new timebase is more
granular.
