The currently when perf TUI report shows callchain, the first level
chains have bogus '+' sign even though only the last one has children.
Since they are on a single line of the chain, toggling intermediate
entries has no effect. Fix it to show '+' sign at the last entry only.
Note that non-first level callchain entries don't have this problem.
