Log creating and destroying of queue for debugging

Crashes has been observed several times in libwayland-client.so with the
following backtrace.

 #0 0x44ff4b56 in wl_list_insert (list=0xb1c03678, elm=elm@entry=0x207c1f8) at /usr/src/debug/wayland-1.20.0/builddir/../src/wayland-util.c:60

I've tried to investigate it and I suppose there is high possibility
that somewhere using libwayland-client could destroy a wl_event_queue
first before all wayland proxies that the queue is associated with.

So, this patch adds log message in where creating and destroying a queue
in the hope that it would help us find the cause of problem next time.
