rofi: 1.7.5 -> 1.7.6 (#369121)

- `racket_7_9` has been removed, as it is insecure. It is recommended to use Racket 8 instead.

- `rofi` has been updated from 1.7.5 to 1.7.6 which introduces some breaking changes to binary plugins, and also contains a lot of new features and bug fixes. This is highlighted because the patch version bump does not indicate the volume of changes by itself. See the [upstream release notes](https://github.com/davatorium/rofi/releases/tag/1.7.6) for the full list of changes.

- `ente-auth` now uses the name `enteauth` for its binary. The previous name was `ente_auth`.

- `fluxus` has been removed, as it depends on `racket_7_9` and had no updates in 9 years.
