Remove imprecise condition of orientation update by translucent activity

The change I4fce2f84254875d0b52252d428000d39f994f14b is enough to
handle the the removed logic in a more precise way.

This avoids clearing rotation transform too early by a translucent
trampoline activity, e.g. portrait activity (X) ->
 landscape translucent activity (Y) -> landscape opaque activity (Z).
Because "r.fillsParent()" is false for (Y), it continues to update
orientation and clear (Z)'s rotation transform. That causes (Z) to
receive extra landscape->portrait->landscape configuration change.
