Deduplicate nix dependency versions (#12307)

# Description
Now we only use `nix 0.28.0`

Achieved by
- updating `ctrlc` to `3.4.4`
- updating `wl-clipboard-rs` to `0.8.1`
- update our own dependency on `nix` from `0.27` to `0.28`
  - required fixing uses of `nix::unistd::{tcgetpgrp,tcsetpgrp}`
  - now requires an I/O safe file descriptor
  - fake one pointing to `libc::STDIN_FILENO` (we were only accessing
`0` previously, dito for fish)


# User-Facing Changes
Better compile times and less to download as source dependencies
