__ini_value: unify `present` + `commented` state awk scripts

Because the difference between the both states is just the comment sign
before it, it was now merged into one folder + symlink to avoid
redundancy. To acomplish the difference, a further parser step was
introduced to execute different print function based on the state (it is
a bit of hard-coded but ok).
