Without TLS initialization, we got the following error on macOS:

* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x0)
    frame #0: 0x0000000100b0defc flb-it-stream_processor`_mk_event_timeout_create(ctx=0x0000000000000000, sec=0, nsec=500000000, data=0x0000600001608460) at mk_event_kqueue.c:222:23
   219         EV_SET(&ke, fd, EVFILT_TIMER, EV_ADD, 0, (sec * 1000) + (nsec / 1000000) , event);
   220     #endif
   221
-> 222         ret = kevent(ctx->kfd, &ke, 1, NULL, 0, NULL);
   223         if (ret < 0) {
   224             close(fd);
   225             mk_libc_error("kevent");
Target 0: (flb-it-stream_processor) stopped.

This can be plugged by TLS initialization for eventloop.
