video_VideoSeek: improve timeout detection

The timeout detection simply consisted in triggering a timeout error if
the test took more than 180 seconds to complete. This can become a short
time to do 100 seeks, especially if the network conditions are not
optimal - as a result, many lab boards were reporting a timeout after
~70 iterations.

Fix this by doing the timeout check not on the whole test, but for each
individual seek: we consider a timeout has occured if we stay more than
60 seconds on the same seek.
