Don't compile app_icon_factory except for ChromeOS.

Compiling app_icon_factory  code triggered compilation errors in some
Windows and Mac builds since the code references app_list which
only exists in ChromeOS. In most builds it was ok because the generated
object file was unused and got stripped by the linker before the dangling
references was found.
