qemu: Add entry for balloon stats stat-htlb-pgalloc and stat-htlb-pgfail

Browse Source 
Qemu added reporting of virtio balloon new statistics stat-htlb-pgalloc and
stat-htlb-pgfail since qemu-3.0 commit b7b12644297. The value of
stat-htlb-pgalloc represents the number of successful hugetlb page allocations
while stat-htlb-pgfail represents the number of failed ones. Add this
statistics reporting to libvirt.

To enable this feature for vm, guest kenel >= 4.17 is required because
the exporting hugetlb page allocation for virtio balloon is introduced
since 6c64fe7f.
