perf tests: Fix shellcheck warning in stat_all_metricgroups

Running shellcheck on stat_all_metricgroups.sh reports
below warning:

 In ./tests/shell/stat_all_metricgroups.sh line 7:
 function ParanoidAndNotRoot()
 ^-- SC2112: 'function' keyword is non-standard. Delete it.

As per the format, "function" is a non-standard keyword that
can be used to declare functions. Fix this by removing the
"function" keyword from ParanoidAndNotRoot function
