Subject: [PATCH] rust: kunit: use crate-level mapping for `c_void`

Use `kernel::ffi::c_void` instead of `core::ffi::c_void` for consistency
and to centralize abstraction.

Since `kernel::ffi::c_void` is a transparent wrapper around
`core::ffi::c_void`, both are functionally equivalent. However, using
`kernel::ffi::c_void` improves consistency across the kernel's Rust code
and provides a unified reference point in case the definition ever needs
to change, even if such a change is unlikely.
