When using the pool security model, _ExecuteKVMRuntime was storing the
instance's UID using str(uid), which would result in storing the
LockedUid.__repr__() result:
$ cat /var/run/ganeti/kvm-hypervisor/uid/xxxxxxxxxxxxx
<ganeti.uidpool.LockedUid object at 0x1f30610>
This patch restores the intended behaviour, by using LockedUid.AsStr().
