ninjabackend: pass objects to doctests

Fix my misunderstanding of the code before commit aede231ef ("ninjabackend:
pass objects to generate_rust_target from non-Rust sources", 2025-07-29).

Object files were added by get_rust_compiler_deps_and_args() to both the
main target and the doctest command lines:

        objs, od = self.flatten_object_list(target)
        for o in objs:
            args.append(f'-Clink-arg={o}')
            deps.append(o)

therefore they now need to be passed as the final argument of
get_rust_compiler_deps_and_args() for both command lines as well.
Failure to do so causes problems building doctests when the main
target has objects as well.

Add a regression test as well.

Fixes: #14897
