rust: add helper for mutex_trylock 



After commit c5b6abab ("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.
