Perf build fails with the new rbtree implementation:

../../lib/rbtree.c:24:36: fatal error: linux/rbtree_augmented.h: No such
file or
directory                                                                                      
compilation terminated.                                                  
make[2]: *** [util/rbtree.o] Error 1                                    
make[1]: *** [perf_install] Error 2                                     
make: *** [tools/perf_install] Error 2

Fix by updating the Makefile and adding a btree_augmented.h wrapper.
