[libvirt][PATCH v15 7/9] qemu_namespace: Create SGX related nodes in domain's namespace

[Lin Yang]

From: Michal Privoznik <mprivozn at redhat.com>

This is similar to the previous commit. SGX memory backend needs
to access /dev/sgx_vepc and /dev/sgx_provision. Create these
nodes in domain's private /dev when required by domain's config.
