lib: rust_support: remove unused `extern_*` functions used for rust

`extern_is_mutex_held` was added at some point to call from Rust,
but it's not anymore (c40c0e386f568b367b3159c2489c3d1cf7d9036e),
and `std::sync::Mutex` doesn't provide such an API either
(though it does provide `.try_lock()`, which `mutex_t` doesn't).

Bug: None
Test: build.py

Builds

Build Status

To build and test for ARM on linux

  1. install or build qemu. v2.4 and above is recommended.
  2. install gcc for embedded arm (see note 1)
  3. run scripts/do-qemuarm (from the lk directory)
  4. you should see ‘welcome to lk/MP’

This will get you a interactive prompt into LK which is running in qemu arm machine ‘virt’ emulation. type ‘help’ for commands.

note 1: for ubuntu: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from http://newos.org/toolchains/arm-eabi-5.3.0-Linux-x86_64.tar.xz
