[PATCH 1/3] perf diff: Fix indentation of stalled backend cycle

[Namhyung Kim <namhyung@kernel.org>]

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