Fix missing resource issue when running on Passion device.

This fixes an issue where the Launcher app will crash with a resource
not found exception when running on a non-xlarge device. The missing
resource(s) are config_workspaceScreenBitmapCacheScale and
config_maxScaleForUsingWorkspaceScreenBitmapCache. These were
introduced in commit bea15195346bab3c52b0156e92f2b71f0811b210. This
change moves those two resources into the common values.
