Although this is implied in your remark, I think it might be helpful to
state it explicitly:

Because kernel headers define interfaces, etc that are *private* to the 
kernel and kernel modules.  To get the interfaces that are safe and
published and *public* for user space programs the headers in 
/lib/modules/`uname -r`/build/include 
are the ones to be used for user space programs.

Even open source programs need some privacy :-)
