erts: Fix system_info({allocator_sizes, mseg_alloc})
will now return
[{instance,0,[{segments_size,9961472,9961472,11010048}]},
{instance,1,[{segments_size,6291456,6291456,6815744}]},

{instance,3,[{segments_size,1048576,1048576,1835008}]},
{instance,4,[{segments_size,0,0,262144}]}]
and not just empty lists.
