Subject: [PATCH] qemu: process: SEV: Assume libDir to be the directory to
 create files in

Since SEV operates on a per domain basis, it's very likely that all
SEV launch-related data will be created under
/var/lib/libvirt/qemu/<domain_name>. Therefore, when calling into
qemuProcessSEVCreateFile we can assume @libDir as the directory prefix
rather than passing it explicitly.
