imagefreeze: clear 0 DTS on buffers output, as sinks will prefer DTS over PTS for syncing

Browse source 
Since the initial decoded still image buffer will have dts=pts=0, and
we only set PTS on buffers we push out, all buffers pushed out would
have a DTS of 0. Sinks, however, will prefer DTS over PTS if both are
set, and will therefore always see a timestamp of 0 no matter what
the PTS is set to.

Fixes unit test too.
