Change the `mrb_vformat` specifier `%d` for `int`

It potentially breaks, for example, in the case of `mrb_int` is 64-bit
and more smaller type is passed by `%d`. In fact, the problem could
become apparent when I used `%d` to `backtrace_location::lineno` in
`src/backtrace.c:mrb_unpack_backtrace()` on AppVeyor.

Therefore, change `%d` for `int` (not `mrb_int`) so that it can be
used mostly without casting.
