    proc: Add sysctl flag CTLFLAG_TUN to loader tunable
    
    The sysctl variable 'kern.kstack_pages' is actually a loader tunable.
    Add sysctl flag CTLFLAG_TUN to it so that `sysctl -T` will report it
    correctly.
    
    No functional change intended.
    
    Note that on arm64 the thread0 stack size can not be controlled with it,
    kib@ suggested that arm64 maintainers can fix it eventually so let's
    enable it also on arm64 right now.
