perf build: Make minimal shellcheck version to v0.6.0

The perf build failed due to the shellcheck on my machine (v0.4.6 on Ubuntu
18.04.1 LTS) doesn't support -a/--check-sourced and -S/--severity option.

These two options are introduced in shellcheck v0.4.7 and v0.6.0
respectively. So restrict the minimal version of shellcheck to v0.6.0.
