relayd: track the health quit pipe with the fd-tracker

Create the relayd health thread quit pipe through the
fd_tracker_util_pipe_open_cloexec() function which wraps
utils_create_pipe_cloexec(), but tracks the resulting file descriptor.

The close of the pipe is also performed through the fd tracker.
