The new uprobe changes bring some new behaviour that we need to reflect in the consumer test. Now pending uprobe instance in the kernel can survive longer and thus might call uretprobe consumer callbacks in some situations in which, previously, such callback would be omitted. We now need to take that into account in uprobe-multi consumer tests. The idea being that uretprobe under test either stayed from before to after (uret_stays + test_bit) or uretprobe instance survived and we have uretprobe active in after (uret_survives + test_bit). uret_survives just states that uretprobe survives if there are *any* uretprobes both before and after (overlapping or not, doesn't matter) and uprobe was attached before.
