[PATCH 3/3] exec/memory: Add symbol for the min value of memory listener priority

[Isaku Yamahata]

Add MEMORY_LISTNER_PRIORITY_MIN for the symbolic value for the min value of
the memory listener instead of the hard-coded magic value 0.  Add explicit
initialization.

No functional change intended.
