  - Require cargo_bin option
    
    The prebuilt cargo (or more precisely, its libstd) cannot be used when
    running cargo2android.py. Ensure that the upstream cargo binary is used.
    This is automatically set when using the sandbox for Googlers. For
    external contributors, raise an error if the option is not provided.
    
    Test: As a googler, execute cargo2android.py directly; an error is
        raised.
    Test: As a googler, use the sandbox; cargo2android.py is executed
        correctly.
    Test: As an external contributor, execute cargo2android.py; an error is
        raised if cargo_bin is not provided.
