This include breaks things for us because hwvulkan.h includes vulkan.h 
from android which has different content than Mesa's vulkan.h. If I make 
this:

#include "hwvulkan.h"

and in Android.vulkan.mk include dir 
"frameworks/native/vulkan/include/hardware", then this won't cause harm 
since I believe that causes us to use mesa's vulkan.h. Harm looks like:

this same happens with bazillions of other functions not included in 
android's old header but present in Mesa's vulkan.h.

no need to include twice

FYI I'm working on to get Android-IA work with these changes. Current 
biggest issue is following:
