It looks like you've got 2 problems here. Not being able to find
runtime_defines.h looks like your install isn't complete (or you are
missing a subpackage). Your next problem is that kernel 4.8 came out
after systemtap 3.0 came out. So, you may need to use systemtap HEAD and
build systemtap from source.
