    samples: rust: fix `rust_print` build making it a combined module
    
    The `rust_print` module, when built as a module, fails to build with:
    
        ERROR: modpost: missing MODULE_LICENSE() in samples/rust/rust_print_events.o
        ERROR: modpost: "__tracepoint_rust_sample_loaded" [samples/rust/rust_print.ko] undefined!
        ERROR: modpost: "rust_do_trace_rust_sample_loaded" [samples/rust/rust_print.ko] undefined!
    
    Fix it by building it as a combined one.
