ubi: tests: Speedup io_paral by using rand_r()
rand() is not thread safe, but glibc seems to use a shared state which is
protected by a mutex. io_paral spawns a few threads and they call rand()
more or less in parallel, which causes heavy lock contention. That
makes the test extremely slow on some setups.
