tests/fate: show seeks on staggered streams, through concat and near an unknown start

Browse Source 
Seek on the later of two AAC streams starting a second apart, remuxed
from one sample, close enough to its start that the seek targets it;
seek through the concat demuxer, which seeks in the file it reads; and
seek close to the start of ADTS, whose start time is unknown.

The references record the current behaviour.
