rust: Fix build break because of "download-rustc" and "llvm-tools"

>From Rust 1.84, the download-rustc and llvm-tools options were set to True
(previously they were False)

rust-lang/rust@cce6f03
(download-rustc)

rust-lang/rust@38f0c09
(llvm-tools)

For tarball sources, the download-rustc option should be False, so it has been
reverted back to False.

Setting llvm-tools to True caused issues with finding llvm-objcopy, so this
has been changed back to False.
