rust: bindings: set HZ to CONFIG_HZ

Browse Source 
include/uapi/asm-generic/param.h defines HZ as __USER_HZ and
include/asm-generic/param.h then sets it to CONFIG_HZ. bindgen keeps the
first definition of a macro and ignores a later #undef, so the generated
binding is __USER_HZ.

Redefine HZ in rust/bindings/lib.rs, the same way compat_ptr_ioctl is
redefined there. Nothing in the tree reads bindings::HZ today, so this
prevents accidental misuse rather than fixing a bug.
