This mirrors what several other subsystems already do with their trace headers (e.g. fs/fuse/fuse_trace.h, fs/gfs2/trace_gfs2.h, fs/lockd/trace.h). As they do, set TRACE_INCLUDE_PATH to "." and add mm/ to the include path of vmscan.o, the only user that defines CREATE_TRACE_POINTS. No functional change.
