    Fix OID format for `vm.swap_reserved` and `vm.swap_total`
    
    The correct OID format for CTLTYPE_U64 is `QU` (`uquad_t`), not `A`
    (text expressed via `char *`).
    
    This issue was noticed while doing an sysctl tree walk using a
    sysctl(9) consumer that relies on the OID format to intuit what the
    type should be for a given sysctl.
