Simon Richter 04154a6517 support/download/cargo-post-process: cargo output for vendor config
Use the output of `cargo vendor` to generate the vendor configuration.

Fixes the need to patch the generated configuration if there are
non-crates.io dependencies.

Note:
  `cargo vendor` currently prints a newline before it prints the
  needed configuration.

  This is fixed in +nightly, will end up in +stable soon and must
  be considered when updating cargo.
  See: https://github.com/rust-lang/cargo/pull/11273

  Until then it is needed to remove this first line to make sure
  that the contents of .cargo/config will be the same as they were
  generated with the earlier version of the script. Thus, the
  hashes of the packages that use this script remain the same.
