Currently meminfo-writer provide a bunch of statistics, which are parsed by qmemman in dom0 and then a single number - used memory. This calculation doesn't require any external knowledge - use only data retrieved from a single VM. So can be done inside of VM, which would simplify data sanitization in qmemman.
The number provided by meminfo-writer should include all in-VM overhead.

This will also ease adding support for qmemman to other systems later.

qmemman-meminfo-writer: send simplified meminfo value
Send just one value - used memory (which is calculated anyway),
instead of full input data. This greatly simplify parsing at qmemman
side.

Fixes QubesOS/qubes-issues#1312
