rust/rusty: Add wrappers for new functions

libunit-wasm added two new functions, luw_req_buf_copy() &
luw_mem_splice_file(). See the previous two commits...

This second function takes a file-descriptor as one of its arguments, in
rusty we make this a Rust File object, then pass the underlying fd into
libunit-wasm.
