Namhyung Kim 4087d11cd9 perf hists browser: Print overhead percent value for first-level callchain
Currently perf report on TUI doesn't print percent for first-level
callchain entry.

I guess it (wrongly) assumes that there's only a single callchain in the
first level.

This patch fixes it by handling the first level callchains same as
others - if it's not 100% it should print the percent value.

Also it'll affect other callchains in the other way around - if it's
100% (single callchain) it should not print the percentage.

Before:
  -   30.95%     6.84%  abc2     abc2              [.] a
     - a
        - 70.00% c
           - 100.00% apic_timer_interrupt
                smp_apic_timer_interrupt
                local_apic_timer_interrupt
                hrtimer_interrupt
                ...
        + 30.00% b
     + __libc_start_main

After:
  -   30.95%     6.84%  abc2     abc2              [.] a
     - 77.90% a
        - 70.00% c
           - apic_timer_interrupt
             smp_apic_timer_interrupt
             local_apic_timer_interrupt
             hrtimer_interrupt
             ...
        + 30.00% b
     + 22.10% __libc_start_main
