[PATCH V2 26/26] tools/perf/tests: Fix shellcheck warning for stat+std_output.sh testcase

[Athira Rajeev]

Running shellcheck on stat_std_output testcase throws
below warning:

   In tests/shell/stat+std_output.sh line 9:
   . $(dirname $0)/lib/stat_output.sh
     ^-----------^ SC2046 (warning): Quote this to prevent word splitting.

   In tests/shell/stat+std_output.sh line 32:
   	   local -i cnt=0
                    ^-^ SC2034 (warning): cnt appears unused. Verify use (or export if used externally).

Fixed the warning by adding quotes to avoid word splitting
and removed unused variable "cnt" at line 32.
