optparse.bash: use `mktemp -t` to safely create temp file #26

Use local build_file="$(mktemp -t "optparse-XXXXXX.tmp")" to create the temp file and to send back the file path

This is similar to

local build_file=${TMPDIR:-/tmp}/optparse-$RANDOM.tmp
touch $build_file
chmod 600 $build_file

but avoids some vulnerabilities.
