perf ftrace: Tidy up the function graph output of 'show' subcommand
Now it doesn't call pevent_print_event() but prints context info in
itself using print_graph_duration(). Make it compact by only print
cpu number and duration:
# perf ftrace show
...
10) 0.065 us | __fsnotify_parent();
10) | fsnotify() {
10) 0.060 us | __srcu_read_lock();
10) 0.040 us | __srcu_read_unlock();
10) 0.652 us | }
10) 0.040 us | fput();
10) | __audit_syscall_exit() {
10) | path_put() {
10) 0.037 us | dput();

10) 0.563 us | }
10) 0.035 us | unroll_tree_refs();
10) 0.035 us | kfree();
10) 1.284 us | }
10) | __audit_syscall_entry() {
