avoid using 'l' as variable

as detected by ruff. try to use a more meaningful variable name instead.

This feels pretty pointless to me.

Do you propose that some combination of ruff+black be used for Portage? I note that you have some black fixes in this PR, do we know why we're not seeing complaints for those in CI?

The black fixes in this PR aren't actually black fixes for portage. They are the classic case of "my first commit introduced some linter errors, so I added a second commit to fix the first commit instead of using git commit --amend".

Overall I agree this seems pointless. Using i as an iteration variable in a loop isn't a bad thing, even if you spell it as an "L" instead.

There are varying opinions on this, obviously. I commented about the general concept on the ruff issue tracker, in fact. :D astral-sh/ruff#4866 (comment)
