fix build of Rust 1.70.0 by disabling download of pre-built LLVM

(created using eb --new-pr)

fix for build failure of Rust-1.70.0-GCCcore-12.3.0.eb:

downloading https://ci-artifacts.rust-lang.org/rustc-builds/90c541806f23a127002de5b4038be731ba1458ca/
rust-dev-1.70.0-x86_64-unknown-linux-gnu.tar.xz
curl: (22) The requested URL returned error: 404

error: failed to download llvm from ci

    help: old builds get deleted after a certain time
    help: if trying to compile an old commit of rustc, disable `download-ci-llvm` in config.toml:

    [llvm]
    download-ci-llvm = false

Build completed unsuccessfully in 0:05:22

This currently only seems to affect Rust 1.70.0, there's no such problem (currently) for older versions (like Rust-1.65.0-GCCcore-12.2.0.eb) and newer version (like Rust-1.73.0-GCCcore-13.2.0.eb).

@boegel could do with a comment explaining what's going on here?

See easybuilders/easybuild-easyblocks#3038 for a more elegant fix :)

[boegel]

@lexming Makes sense to update the easyblock, this was more of a stop-gap solution since I wasn't sure whether older Rust versions were going to be a problem (looks like that's a no).

I'll close this, people can still use eb --from-pr 19264 to work around this issue until the next EasyBuild release (most likely v4.9.0) that includes easybuilders/easybuild-easyblocks#3038 is out .
