Subject: [PATCH] tests: define __STDC_LIMIT_MACROS

With glibc 2.16, we get following build error when building jack2:

  [193/247] cxx: tests/iodelay.cpp -> build/tests/iodelay.cpp.4.o
  ../tests/iodelay.cpp:171:43: error: 'UINT32_MAX' was not declared in this scope
  ../tests/iodelay.cpp:171:55: error: 'UINT32_MAX' was not declared in this scope
  ../tests/iodelay.cpp:172:44: error: 'UINT32_MAX' was not declared in this scope
  ../tests/iodelay.cpp:172:56: error: 'UINT32_MAX' was not declared in this scope

In glibc 2.17 or older version, Header <stdint.h> defines these macros
for C++ only if explicitly requested by defining __STDC_LIMIT_MACROS.

We can't use <cstdint> since it requires C++11 standard.

This build issue found by Buildroot autobuilder.
