py/objint: Allow to print long-long ints without using the heap.
Some stack is allocated to format ints, and when the int implementation uses
long-long there should be additional stack allocated compared with the other
cases. This patch uses the existing "fmt_int_t" type to determine the
amount of stack to allocate.
