[PATCH V2 24/26] tools/perf/tests/shell/lib: Fix shellcheck warning for stat_output.sh shell script

[Athira Rajeev]

From: Kajol Jain <kjain at linux.ibm.com>

Running shellcheck on stat_output.sh throws below warning:

In tests/shell/lib/stat_output.sh line 1:
^-- SC2148 (error): Tips depend on target shell and yours is unknown. Add a shebang or a 'shell' directive.

Fixed the warning by adding shell directive.
