rust: add helper for mutex_trylock
After commit c5b6ababd21a ("locking/mutex: implement mutex_trylock_nested",
currently in the KVM tree) mutex_trylock() will be a macro when lockdep is
enabled. Rust therefore needs the corresponding helper. Just add it and
the rust/bindings/bindings_helpers_generated.rs Makefile rules will do
their thing.
