[refpolicy] [PATCH 1/3]libsemanage Fix warning: parameter 'key' set but not used(and others)

[Justin P. Mattock]

libsemanage produced no errors with the warnings, Im just noticing
big hunks of sections with warning messages:

database_llist.c: In function 'dbase_llist_add':
database_llist.c:150:28: warning: parameter 'key' set but not used
database_llist.c: In function 'dbase_llist_count':
database_llist.c:221:50: warning: parameter 'handle' set but not used
database_llist.c: In function 'dbase_llist_del':
database_llist.c:278:41: warning: parameter 'handle' set but not used
(and so on...)
so add the GCC attribute to quiet these warnings since most go to
NULL;
