sprintf error on ARMv7 with MRB_INT64

[kazuho]

I get following error when running make test on 32-bit ARM with MRB_INT64.

Fail: String#% (mrbgems: mruby-sprintf)
 - Assertion[1] Failed: Expected to be equal
    Expected: "one=1"
      Actual: "one=0"
 - Assertion[2] Failed: Expected to be equal
    Expected: "1 one 1.0"
      Actual: "0 one 1.0"

I assume this is because the implementation unconditionally uses sprintf "%l?" to stringify the value at line https://github.com/mruby/mruby/blob/master/mrbgems/mruby-sprintf/src/sprintf.c#L858.

@kazuho could you check the new code 7c82bfa?
