Currently bindgen has special logic to recognise `size_t` and `ssize_t` and map them to Rust `usize` and `isize`. Similarly, `ptrdiff_t` is mapped to `isize`. However this falls short for `__kernel_size_t`, `__kernel_ssize_t` and `__kernel_ptrdiff_t`. To ensure that they are mapped to usize/isize rather than 32/64 integers depending on platform, blocklist them in bindgen parameters and manually provide their definition.
