Allow to specify RUSTDOCFLAGS independently
Currently, if you to run this experiment: ``` cargo run -- define-ex --ex rustdoc-json-broken --mode rustdoc \ --cap-lints warn --crate-select list:serde \ "nightly-2022-06-01+rustflags=-Z unstable-options --output-format json" \ "nightly+rustflags=-Z unstable-options --output-format json" \ ``` crater will mix up `RUSTFLAGS` and `RUSTDOCFLAGS` and you will get the following error: ``` [INFO] [stderr] process didn't exit successfully: `rustc - --crate-name ___ \ --print=file-names --cap-lints=warn -Z unstable-options --output-format json \ --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib \ --crate-type staticlib --crate-type proc-macro --print=sysroot --print=cfg` \ (exit status: 1) [INFO] [stderr] --- stderr [INFO] [stderr] error: Unrecognized option: 'output-format' ``` Solve this by allowing `rustdoc` and `rustdocflags` to be specified independently. After this change, this works without unexpected errors: ``` cargo run -- define-ex --ex rustdoc-json-ice --mode rustdoc \ --cap-lints warn --crate-select list:serde \ "nightly-2022-06-01+rustdocflags=-Z unstable-options --output-format json" \ "nightly+rustdocflags=-Z unstable-options --output-format json" ```
