In b1e2c3453f50cc05a1b03dc1c8571a01ad7b7dd2, the `res.users.settings`
model was moved from `mail/` to `base/`, but its record rules remained
in `mail/`. This means that if `mail/` is not installed, users will be
able to access other users' `res.users.settings` records. In practice,
this is not a problem, as the only field that can exist in
`res.users.settings` without `mail/` is `homemenu_config`, which
contains nothing senstive.
This commit moves the forgotten record rules to `base/`, preventing
potential problems if new fields with sensitive information were to be
added to `res.users.settings` in the future.
