scx.full: don't build on aarch64-linux

As per https://github.com/NixOS/nixpkgs/pull/381138#issuecomment-2653368487
scx releases often breaks building on aarch64-linux, and besides the package
does not seem to have proper support for this platform

This reverts commit 0f40303097.

This can be reverted again if we feel upstream has improved its aarch64-linux support.
