1. selftests: override KHDR_INCLUDES var …

   In a recent series [1], I suggested to use KHDR_INCLUDES variable to
   avoid having to duplicate UAPI header files.
   
   The BPF CI builds the kernel in a separated directory -- KBUILD_OUTPUT
   variable is set and exported -- and the BPF selftests are executed
   directly, from the selftests/bpf directory, not from its parent. In thi
   s case, it is required to override KHDR_INCLUDES to look at the build
   directory, and not the kernel source, in 'usr/include'.
   
   Note that tools/testing/selftests/Makefile supports KBUILD_OUTPUT, but
   this Makefile is not used by the BPF CI: it directly uses the one from
   the bpf directory: tools/testing/selftests/bpf/Makefile. That's fine,
   KHDR_INCLUDES can be overridden, that should then fix the build issue
   seen in [1].
   
   Also, this KHDR_INCLUDES variable is not used by the BPF selftests
   before my series [1]. It is then fine to merge this modification before
   applying my modifications.
