Use snprintf for random unique indexes 

Replace sprintf with VL_SNPRINTF when formatting unique-array SMT select indexes. Apple clang marks sprintf deprecated under the current SDK, and --enable-ccwarn promotes that warning to an error when tests compile verilated_random.cpp.

Evidence: t_process.py failed before the change at include/verilated_random.cpp:499 with -Wdeprecated-declarations; after the change, t_process.py and t_randomize_unique_elem.py pass.
