nixos/weechat: add setuid wrapper for `screen' to ensure true multiuser capabilities
Previously you either had to set the setuid bit yourself or workaround
`isSystemUser = true` (for a loginable shell) to access the weechat
screen.

`programs.screen` shouldn't do this by default to avoid taking too much
assumptions about the setup, however `services.weechat` explicitly
requires tihs.

See #45728
