Title: Reduce sprintf() calls. Remove mrb_int_to_str() and MRB_INT_FORMAT.

sprintf() is defined in stdio.h. So it can't use if there is no stdio.h on target environments.
This fix doesn't remove all sprintf() in the repository. Just reduce.

This patch provides a happy side effect. We can remove MRB_INT_FORMAT macro.
