Fix incorrect strip position if pitch was animated

Commit 302b04a5a3fc introduced new retiming system, that unified sound
pitch animation with strip speed control. Because sound playback is
handled in different way, this did not work as expected and old files
were broken. In addition animation was not copied to new property.

Revert length position and offset handling for sound strips so their
position does not change and remap fcurves to new `speed_factor`
property.
