virt-manager needs to know if memfd memory source type is supported in
order to use virtiofs.

New subject: [PATCH 1/2] conf: domcaps: Report <memoryBacking>
We need to report via domcapabilities if specifying shared memory
is supported without hugepages or numa config in order to find
out if domain has suitable setup to make virtiofs work.
The solution is to report source types of memory backing to
determine if memfd is a valid option.
