rust: declare self as qemu_api for proc-macros

Fix an outstanding TODO.

Declaring `extern crate self as qemu_api` allows use of `qemu_api`
within the qemu_api crate; this allows the Wrapper derive macro and
future proc macros to be used interchangeably in the qemu_api crate and
other crates. This is not required currently and is only for
future-proofing.
