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".
