fontchooserwidget: Simplify function

- Don't do unnecessary casts
- Fix weird variable declaration indenting
- Fix loop indentation
- Use a for loop for iterating over a list, instead of a while loop
- Casefold font name only once, instead of every iteration
- Remove needless true_var = true_var && TRUE assignment
