poll-loop: Log backtraces when CPU usage is high.

Often when debugging Open vSwitch, one will see in the logs that
CPU usage has been high for some period of time, but it's totally
unclear why.  In an attempt to remedy the situation, this patch
logs backtraces taken at regular intervals as a poor man's
profiling alternative.
