perf test stat+shadow_stat.sh: Add threshold for rounding errors
The test was failing in specific scenarios due to imperfection of FP
arithmetics. The `bc` command wasn't correctly rounding the result of
division causing the failure.
Replace the `bc` with `awk` which should work with more decimal places
and add a threshold to catch any possible rounding errors. The
acceptable rounding error is set to 0.01 when the test passes with a
warning message.
