tools/lib has a 1.1.0 copy of libtraceevent. If a newer system
version is installed then its headers will go in /usr/include. As -I has
priority over system headers the 1.1.0 version gets used in preference
to the system one, which isn't what is wanted. To make the behavior
match expectations use -idirafter so that any system headers have priority
over the tools/lib version.
Fixes: 08efcb4a638d ("libtraceevent: Increase libtraceevent logging when verbose")
