vmstat: Fix duplicate key in libxo output

[allanjude]

Summary

In the libxo output from vmstat, the number of pages that have been paged out uses the same key name as the number of time
pages have been paged. Appears to have been a typo or copy-pasto.

Hi @phil

i discovered this when executing go vet command

https://github.com/sternix/gobsdinfo/blob/master/mem/sum.go#L24

" sum.go:25: struct field VnodePageOutPages repeats json tag "vnode-page-outs" also at sum.go:23 "

FYI
