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.

Steven: please feel free to rebase the original if that is better for
you, but in case you prefer a formal patch on top, here it is. Thanks!
