  qemu: Prefer hugepages over mem source='file'

https://bugzilla.redhat.com/show_bug.cgi?id=1214369

Consider the following XML:

<memoryBacking>
<hugepages>
<page size='2048' unit='KiB' nodeset='1'/>
</hugepages>
<source type='file'/>
<access mode='shared'/>
</memoryBacking>

<numa>
<cell id='0' cpus='0-3' memory='512000' unit='KiB'/>
<cell id='1' cpus='4-7' memory='512000' unit='KiB'/>
</numa>

The following cmd line is generated:

-object
memory-backend-file,id=ram-node0,mem-path=/var/lib/libvirt/qemu/ram,
share=yes,size=524288000 -numa node,nodeid=0,cpus=0-3,memdev=ram-node0
-object
memory-backend-file,id=ram-node1,mem-path=/var/lib/libvirt/qemu/ram,
share=yes,size=524288000 -numa node,nodeid=1,cpus=4-7,memdev=ram-node1

This is obviously wrong as for node 1 hugepages should have been
used. The hugepages configuration is more specific than <source
type='file'/>.
