perf stat: Fix indentation of stalled backend cycle
The commit 140aeadc1fb5 ("perf stat: Abstract stat metrics printing")
changed how shadow metrics are printed, but it missed to update the
width of the stalled backend cycles event to 7.2% like others. This
resulted in misaligned output like below:
