jpegparse: Do not set the duration to the input buffer's duration unless valid

Browse Source 
This causes a bug where the first buffer has ts = 0, dur=X, the second buffer
has ts=X (because of ts += duration), dur=-1, then the following buffers
will start having a non valid timestamp.
The real duration is only calculated during the caps negociation when there
is a framerate available and the buffer's duration is invalid.
