perf beauty arch_errno_names: Fix shellcheck issue about local variables

Running shellcheck on arch_errno_names.sh generates below warning:

In arch_errno_names.sh line 20:
	local arch="$1"
        ^--------^ SC3043 (warning): In POSIX sh, 'local' is undefined.

......

In arch_errno_names.sh line 61:
	local arch
        ^--------^ SC3043 (warning): In POSIX sh, 'local' is undefined.

In arch_errno_names.sh line 67:
		printf '\t\treturn errno_to_name__%s(err);\n' $(arch_string "$arch")
                                                              ^--------------------^ SC2046 (warning): Quote this to prevent word splitting.

In arch_errno_names.sh line 69:
	printf '\treturn errno_to_name__%s(err);\n' $(arch_string "$default")
                                                    ^-----------------------^ SC2046 (warning): Quote this to prevent word splitting.

Fixed the warnings by:
- Fixing shellcheck warnings for local usage, by removing
  local from the variable names
- Adding quotes to avoid word splitting
