I don't think this necessarily needs to be a separate function, I think it would be best just to put the check inline. I can appreciate having the function names clearly express what is being done, but wrapping single expressions like this tends to significantly increase the total lines of code.

I think these checks will need to be starts_with since you can have something like --crate-version=foo.

I don't think it is necessary to define a whole separate test. To avoid the repetition, at the bottom of the other test, call p.build_dir().rm_rf(); and then p.cargo("rustdoc …"), and then check the results again (can maybe put the asserts in a closure so they aren't repeated).

I'm thinking it might be a little simpler just to check the args of the ProcessBuilder instead of re-fetching the extra args/rustdocflags.
So, move the call to add_crate_versions_if_requested after the args are added to the builder, and call something like this:
rustdoc.get_args().iter().any(|flag| {
flag.to_str().map_or(false, |s| s.starts_with(RUSTDOC_CRATE_VERSION_FLAG))
})
