[PATCH 6.18 096/122] scripts: generate_rust_analyzer: remove sysroot assertion

From: Onur Özkan <work@onurozkan.dev>

commit 1b83ef9f7ad4635c913b80ef5e718f95f48e85af upstream.

With nixpkgs's rustc, rust-src component is not bundled
with the compiler by default and is instead provided from
a separate store path, so this assumption does not hold.

The assertion assumes these paths are in the same location
which causes `make LLVM=1 rust-analyzer` to fail on NixOS.
