perf tests lock_contention: Fix shellcheck issue about quoting to avoid word splitting

Running shellcheck on lock_contention.sh generates below warning:

In tests/shell/lock_contention.sh line 24:
	if [ `id -u` != 0 ]; then
             ^-----^ SC2046 (warning): Quote this to prevent word splitting.

In tests/shell/lock_contention.sh line 160:
	local type=$(head -1 "${result}" | awk '{ print $8 }' | sed -e 's/:.*//')
        ^--------^ SC3043 (warning): In POSIX sh, 'local' is undefined.
              ^--^ SC2155 (warning): Declare and assign separately to avoid masking return values.
                   ^-- SC2046 (warning): Quote this to prevent word splitting.

Fixed above warnings by:

- Adding quotes to avoid word splitting.
- Fixing shellcheck warnings for local usage, by prefixing
  function name to the variable.
