file-restore: increase lock timeout on QEMU map
This lock is held during VM startup, so that multiple calls will not start VMs twice. But this means that the timeout needs to incorporate the time it might take a VM to boot, so increase it quite a bit. This could previously lead to "interrupted system call" errors when accessing backups with many disks. Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
