ZOOKEEPER-2932 Performance enhancement about purging task.
The method FileTxnLog.getLogFiles is used to find out the target log files
to be retained base on the given zxid when purging task is running. The current
implementation of this method is trivial to understand, and iterate the log
files twice to achieve its purchase. It could be improved from both performance
and readability.
