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

Browse Source 
The first check on the enum values was not necessary as the values set
in wait_event_names.txt for the classes LWLock and Lock were able to
satisfy the check.  The second check when generating the C and header
files is now based on a match of the class names, making it simpler to
understand.
