Fix runtime crash on KitKat and prior.

This is a follow up CL to the previous CL [1], in which we started
calling Window#setNavigationBarColor(int) when the window visibility is
changed.

One thing we missed is that calling Window#setNavigationBarColor(int) on
KitKant or prior devices would result in a runtime crash.  Hence with
this CL we do not call that method unless the OS version is N or leter,
because specifying Color.TRANSPARENT would make sense on N+ devices.
