Simplify some conditions related to [LW]Lock in generate-wait_event_types.pl

The first check on the enum values was not necessary as the values setin wait_event_names.txt for the classes LWLock and Lock were able tosatisfy the check. The second check when generating the C and headerfiles is now based on a match of the class names, making it simpler tounderstand.Author: Masahiro Ikeda, Michael PaquierDiscussion:https://postgr.es/m/eaf82a85c0ef1b55dc3b651d3f7b867a@oss.nttdata.com
