lang/rust: Update to 1.31.1

- Simplify .cargo-checksum.json handling [1].  Similar to USES=cargo
  we disable vendor checksum checking by clearing the list of files
  in all .cargo-checksum.json, so that cargo does not complain when
  we patch something.  The overall distfile is already checked by
  us which should be enough.
- Add an overridable CARGO_VENDOR_DIR variable to set the crate
  vendor directory which has moved location in nightly
- Add upstream openssl-sys patch to fix build with LibreSSL 2.9.0 [2]
