perf tools: Collapse first level callchain entry if it has sibling

If first level callchain has more than single path like when -g caller
option is given, it should show only first one in the path and hide
others.  But it didn't do it properly and just hindered the output.

Before:
  -   80.33%    11.11%  abc2     abc2              [.] main
     + 86.18% main
       13.82% __libc_start_main
          main

After:
  -   80.33%    11.11%  abc2     abc2              [.] main
     + 86.18% main
     + 13.82% __libc_start_main
