tools/virtio: fix up compiler.h stub



Add #undef __user before and after including compiler_types.h to avoid
redefinition warnings when compiling with system headers that also
define __user. This allows tools/virtio to build without warnings.

Additionally, stub out __must_check

Created using Cursor CLI.
