Planner: Unify final ascent rates in plan() and fake_dc()
When generating fake profiles for manually entered dives, fake_dc() and
plan() used different final ascent rates of 5 m/min and 4.5 m/min,
respectively. This led to dives that were 6 seconds longer than entered
by the user and to confusion. See #554.
Therefore, use the same ascent rate taken from the preferences field
flag.ascratelast6m in both cases.
