The Rust Binder object file is called rust_binder_main.o because the
name rust_binder.o is used for the result of linking together
rust_binder_main.o with rust_binderfs.o and a few others.

However, the crate name is supposed to be rust_binder without a _main
suffix. Thus, override the crate name accordingly.
