Fix T95378: Seek problems when timecodes are used
Function `IMB_indexer_get_seek_pos()` can return non 0 seek position for frame index 0. This causes seeking to incorrect GOP and scanning ends with failiure. Hard-code first frame index seek position to 0. Differential Revision: https://developer.blender.org/D13974
