[PATCH v4 0/2] Change Rust Binder crate name to rust_binder

[Alice Ryhl <aliceryhl@google.com>]

Currently the crate name of the Rust Binder driver is rust_binder_main,
but I'd like it to be called rust_binder instead, matching the .ko file.
This affects e.g. symbol names in stack traces.

Thus, allow use of the #![crate_name] annotation, and set it for Rust
Binder.

I tried just using RUSTFLAGS_stem.o and RUSTFLAGS_REMOVE_stem.o, but
RUSTFLAGS_REMOVE_ is incapable of removing the --crate-name argument.
(Even after changing --crate-name to be passed with = instead of space
as the separator to the name.)

This cross-subsystem series is intended to be merged via rust-next.
