[PATCH V2 22/26] tools/perf/tests/shell: Fix the shellcheck warnings in record+zstd_comp_decomp.sh

[Athira Rajeev]

Running shellcheck on record+zstd_comp_decomp.sh testcases
throws below warning:

   In tests/shell/record+zstd_comp_decomp.sh line 16:
       	   $perf_tool record -o $trace_file $gflag -z -F 5000 -- \
                                ^---------^ SC2086 (info): Double quote to prevent globbing and word splitting.

   Did you mean:
     	   $perf_tool record -o "$trace_file" $gflag -z -F 5000 -- \

   In tests/shell/record+zstd_comp_decomp.sh line 22:
	   $perf_tool report -i $trace_file --header --stats | \
                                ^---------^ SC2086 (info): Double quote to prevent globbing and word splitting.

Added double quote around file names to fix these
shellcheck reported issues.
