avformat/lavfi: force probesize to cover at least 30 frames
This ensures that fps and other values are estimated correctly,
the probesize also is intended to limit disk/protocol reads which
does not apply to lavfi inputs at all.
Fixes Ticket1051
Something similar could be usefull to other input devices
