rpm_5.1.10: Disable dependency loop message

[BUGID #332]

Disable the dependency loop message that looked like an error had
occured.  This is really a debug message.

Also remove the "remove: " debug message about which side of the
dep loop it is removing to resolve the circular dependency.

+The LOOP: ... messages appear to be errors, but in reality they are
+simply debug messages that indicate there is one or more dependency
+loop within the system.
+
+Due to Poky packages owning all of the directories they use, a large
+number of depedency loops may be present.  So disabling this message
+seems to make the most sense.
