Inline CStr::from_bytes_with_nul_unchecked::rt_impl

Currently `CStr::from_bytes_with_nul_unchecked::rt_impl` is not being inlined. The following function:

```rust
pub unsafe fn from_bytes_with_nul_unchecked(bytes: &[u8]) {
    CStr::from_bytes_with_nul_unchecked(bytes);
}
```

Outputs the following assembly on current nightly

```asm
example::from_bytes_with_nul_unchecked:
        jmp     qword ptr [rip + _ZN4core3ffi5c_str4CStr29from_bytes_with_nul_unchecked7rt_impl17h026f29f3d6a41333E@GOTPCREL]
```

Meanwhile on beta this provides the following assembly:

```asm
example::from_bytes_with_nul_unchecked:
        ret
```

This pull request adds `#[inline]` annotation to`rt_impl` to fix a code generation regression for `CStr::from_bytes_with_nul_unchecked`.
