runtime: Fix printing failed allocation amounts.

On LP64 and LLP64 systems, size_t is bigger than unsigned.
Printing the failed allocation as mp_uint_t allows the correct failed
allocation size to be shown.

However, there are occasions where mp_uint_t is bigger than size_t
(nanbox).  In that case, preserve the existing code path to avoid
growth in executable size.

Example where this affects the failed allocation message (on x86_64
coverage build):
```
>>> "a" * (1 << 54)
```

Before, this would print the size as 1.  Now it prints it as
18014398509481985 (2**54 + 1).
