[pve-devel] [PATCH qemu-server] fix #2857: restore: pass keyfile to pbs-restore

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

if configured. otherwise restoring encrypted backups will be quite
hard..

Signed-off-by: Fabian Grünbichler <f.gruenbichler@proxmox.com>

Note: for restore to actually work, we need pbs-restore linked with a
bumped libproxmox-backup-qemu which has all the recent changes w.r.t.
encryption. we might want to bump pve-qemu-kvm as well to encode these
breaking changes in package relations, or add a libproxmox-backup-qemu
dependency in qemu-server?
