perf tests stat+shadow_stat.sh: Fix all POSIX sh warnings found using shellcheck

Running shellcheck -S on stat+shadow_stat.sh testcase, generates
SC2046 and SC2034 warnings,

$ shellcheck -S warning tests/shell/stat+shadow_stat.sh
	res=`printf "%.2f" $(echo "scale=6; $num / $cyc" | bc -q)`
			   : Quote this to prevent word splitting

To address the POSIX shell warnings used quotes in the printf
expressions, to prevent word splitting.
