kutil/queue: use util_snprintf() in util_queue_init

kutil/queue: use util_snprintf() in util_queue_init

Instead of plain snprintf(). To fix the MSVC 2013 build:

  Compiling src\util\u_queue.c ...
u_queue.c
src\util\u_queue.c(325) : warning C4013: 'snprintf' undefined; assuming extern returning int

...

mesautil.lib(u_queue.obj) : error LNK2001: unresolved external symbol _snprintf
scons: building terminated because of errors.
