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.

v2:
- Instead of renaming the module name, rename the main source file.
This avoids changing other places (e.g. Kconfig) and, most
importantly, minimizes the impact to developers/users (e.g. CIs
out there).
