Miguel Ojeda 499dc02cd5 rust: zerocopy: add SPDX License Identifiers ...

Originally, when the Rust upstream `alloc` standard library crate was
vendored, the SPDX License Identifiers were added to every file so that
the license on those was clear. The same happened with the vendoring of
`proc_macro2`, `quote` and `syn`. Please see:

  commit 057b8d2571 ("rust: adapt `alloc` crate to the kernel")
  commit 69942c0a89 ("rust: syn: add SPDX License Identifiers")
  commit ddfa1b279d ("rust: quote: add SPDX License Identifiers")
  commit a9acfceb96 ("rust: proc-macro2: add SPDX License Identifiers")

Thus do the same for the `zerocopy` crate.

This makes `scripts/spdxcheck.py` pass: use parentheses like commit
06e9bfc1e5 ("ionic: make spdxcheck.py happy") did since we have two
`OR` operators in the expression (three licenses).

SPDX identifiers are not added to the `benches` files because they are
included in rendered documentation. Nevertheless, the `README.md` to be
added by a later commit mentions the license.

Finally, as requested, I filed an issue [1] with upstream about it.
