mmap18: Increase minimal stack mapping to PTHREAD_STACK_MIN

The first testcase keeps segfaulting on older kernels with only 4KB initial stack mapping. Pthread man pages say that stack must be at least PTHREAD_STACK_MIN bytes in size but they're not clear how that relates to growing stacks. Let's be on the safe side.
