unix: add Uvmexp and SysctlUvmexp for NetBSD NetBSD has both struct uvmexp (used internally) and struct uvmexp_sysctl (preferred for interfacing from user code). Expose the latter as type Uvmexp with the same interface as on OpenBSD. I am not sure if it makes sense to even have a name parameter for SysctlUvmexp, since the only valid value can be "vm.uvmext2".
