Adjust OOM kill detected rule

Browse source 
When a machine runs out of memory, it happens that the node
exporter stops responding for multiple minutes. I've adjusted
the rule now to take this into account: even if it takes 15-20
minutes before the machine becomes responsive again, the
alert should still fire.
