    objtool/rust: relax slice condition to cover more `noreturn` Rust functions

    Developers are indeed hitting other of the `noreturn` slice symbols in
    Nova [1], thus relax the last check in the list so that we catch all of
    them, i.e.

        *_4core5slice5index22slice_index_order_fail
        *_4core5slice5index24slice_end_index_len_fail
        *_4core5slice5index26slice_start_index_len_fail
        *_4core5slice5index29slice_end_index_overflow_fail
        *_4core5slice5index31slice_start_index_overflow_fail

    These all exist since at least Rust 1.78.0, thus backport it too.

    See commit 56d680d ("objtool/rust: list `noreturn` Rust functions")
    for more details.
