The code removed by this revision was added at a time any user
could access the `res.config.settings` model, including non-admins.

So, it made sense at the time to make the module installation checkboxes
readonly for non-admin users accessing the settings.

However, since revision
https://github.com/odoo/odoo/commit/65530dfd6a0486f44134917f5cc42a2c30b95762#diff-e275aaa5de11da2815c2f0cc18bc046f967df5e4eba94999ee55ffe8926c87bdR109


the `res.config.settings` model is restricted to admins only,
who have the write access the `ir.module.module` model.

This override is therefore pointless,
as since then it's impossible for non-admins to access
the settings.
