Fix log tail rotation handling and SIGHUP cleanup

- Detect IN_MOVE_SELF/IN_DELETE_SELF events in log_tail_handle and
  re-open the watched path so srcds log rotation is followed correctly
- Parse inotify events rather than blindly draining them
- Call log_tail_cleanup() before log_tail_init() on SIGHUP to prevent
  fd leaks on reload
