sd_lavc: compensate for a stupid libavcodec API issue
The libavcodec PGS decoder sets end_display_time to UINT32_MAX, in an attempt to signal unknown end time (the API does not allow to signal this properly, and this was a backwards compatible hack). While we have no issues with the large value, our code wants to distinguish between known and unknown end time explicitly.
