fix(android): fix mapbuffer jni headers not found consuming react-native from prefab

[hannojg]

Summary:

I was getting build errors when I tried to include StateWrapperImpl.h in my library's code on android. The error was:

node_modules/react-native/ReactAndroid/build/prefab-headers/reactnative/react/fabric/StateWrapperImpl.h:11:10: fatal error: 'react/common/mapbuffer/JReadableMapBuffer.h' file not found
#include <react/common/mapbuffer/JReadableMapBuffer.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3 warnings and 1 error generated.

The problem is that the map buffer files inside the mapbuffer folder are nested, so the prefab outcome looks like this:

Hence it can't resolve the header path.

This change removes the header prefix part as its not needed, since the nested folder structure in mapbuffer already matches what we need, see:

Changelog:

[ANDROID] [FIXED] - Fixed build issue when including mapbuffer jni headers in library code

Test Plan:

make sure the header path looks correct in the prefab build dir:

Thanks for fixing this

Sure! Do I need to do something about the failing CI? (the failed CI runs are iOS and this is a android only change so I am confused to why they failed)
