drop the x1e packages; they live in x1e-nixos now

qebspil, slbounce, tcblaunch, x1e80100-firmware and x1e80100-linux-firmware
only ever had the Surface Laptop 7 NixOS modules as consumers, and keeping
them a repo away meant every firmware bump was a two-repo dance. They now
ship from git.scug.io/nikkuss/x1e-nixos, which adds its own overlay.

ath-tools stays: it is generic ath12k tooling rather than x1e-specific, even
though its only consumer here left with the firmware package.
