Reviewed by Antonio Gomes.

Source/WebCore:

The m_userDrivenSeekTimer is causing unwanted repeats of short
media such as sound effects because it is causing the current
time to not reflect that the media has finished playing.
This problem only affects media whose duration is close to
or less than the SeekSubmissionDelay, which is currently
set to 100ms. My fix is to ignore the userDrivenSeekTimer in
MediaPlayerPrivate::currentTime() if the duration of the media
is within twice the SeekSubmissionDelay. Seek drag smoothness
is a non-issue for such short media.
