[PATCH 21/22] tools/perf/trace: Fix x86_arch_prctl.sh to address shellcheck warnings

[Athira Rajeev <atrajeev@linux.vnet.ibm.com>]

Running shellcheck on x86_arch_prctl.sh generates below warning:

  In ./tools/perf/trace/beauty/x86_arch_prctl.sh line 10:
      	local idx=$1
        ^-------^ SC3043 (warning): In POSIX sh, 'local' is undefined.

  In ./tools/perf/trace/beauty/x86_arch_prctl.sh line 11:
	local prefix=$2
        ^----------^ SC3043 (warning): In POSIX sh, 'local' is undefined.

   In ./tools/perf/trace/beauty/x86_arch_prctl.sh line 12:
	local first_entry=$3
        ^---------------^ SC3043 (warning): In POSIX sh, 'local' is undefined.

Fix this by removing local since these are variables
used only in specific function
