The source for Rust's 'core' library is needed to build the kernel with Rust support. This must be obtained manually when using a non-rustup install, such as when using 'rustc' from a package manager or from a standalone installer. Currently, the documentation suggests cloning the 'rust' repository to obtain these sources, but this is quite slow (on the order of a few minutes). This patch changes this documentation to suggest using the source tarball instead, which includes only needed information (<5M) and is significantly faster to download. This is more in line with what 'rustup' does.
