Partial revert of "Align Theme, Theme.Holo, and Theme.Holo.Light with Material attrs"

This partially reverts commit 045abe73.

Basically we're just removing the attributes that were explicitly
defined as null, since apparently they don't have fallback values
unless Holo is overlaid atop Material (blergh).
