The `make rustavailable` process expects the Rust standard library source files

Help kernel newbies by saying:
The `make rustavailable` process (1) expects the Rust standard library source
files (e.g., `lib.rs`)
and then in the footer:
1) See the kernel tree for Documentation/rust/quick-start.rst in the section:
Requirements: Building
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/rust/quick-start.rst#n145
../Randy
to be present in the `library/` directory under `rustlib/src/rust/`.
This patch ensures the required sources are available by:
- Copying the `library/` directory from the Rust source tree into
`${TMPDIR}/work-shared/rust`
during the snapshot setup.
- Installing the `library/` directory into
`${SDKPATHNATIVE}/usr/lib/rustlib/src/rust` for the
`nativesdk` class, making them available in them available in sdk
