plugin-api: resourced: Add lmk_try_count in get_kill_candidates_post_with_wss

resourced-lmk-governor needs to know the number of killing cycle.
This is because, the governor should know whether
memory thrasing happens or not. If lowmem state is not recovered during the
threshold cycle, then the governor skips working set size calculation and
does not give benefit to apps with effcient memory usage.
