rust: proc-macro2: add SPDX License Identifiers

2025-11-24T16:15:39+00:00

Originally, when the Rust upstream `alloc` standard library crate was vendored in commit 057b8d257107 ("rust: adapt `alloc` crate to the kernel"), the SPDX License Identifiers were added to every file so that the license on those was clear. Thus do the same for the `proc-macro2` crate. This makes `scripts/spdxcheck.py` pass.
