Sebastian Dröge 3172bcd095 fmp4mux: Crank clock for the first fragment in more tests 
Due to how aggregator works, it depends on how buffers are pulled
whether aggregate() is called again or it is waiting for a timeout or EOS:

works:
  - pad 1: 4 buffers, pad 2: 4 buffers
  - aggregate ready: take all 4/4 buffers
  - pad 1: 1 buffers, pad 2: 1 buffer
  - aggregate ready: take all 1/1 buffers

waits:
  - pad 1: 5 buffers, pad 2: 4 buffers
  - aggregate ready: take all 5/4 buffers
  - pad 1: 0 buffers, pad 2: 1 buffer
  - aggregate not ready: waiting for timeout or EOS

Also don't manually set the clock time as that's unnecessary.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/issues/274
