[PULL 30/30] exec/memory: Add symbol for the min value of memory listener priority

[Philippe Mathieu-Daudé]

From: Isaku Yamahata <isaku.yamahata@intel.com>

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.
