PR libstdc++/54576: random_device isn't protected by _GLIBCXX_USE_C99_STDINT_TR1

[H.J. Lu]

Hi,

include/random has

#ifdef _GLIBCXX_USE_C99_STDINT_TR1

#include <cstdint> // For uint_fast32_t, uint_fast64_t, uint_least32_t
#include <bits/random.h>
#include <bits/random.tcc>

#endif // _GLIBCXX_USE_C99_STDINT_TR1

random_device is defined in <bits/random.h>. But src/c++11/random.cc
has

#include <random>
...
  void
  random_device::_M_init(const std::string& token)
  {

It doesn't check if _GLIBCXX_USE_C99_STDINT_TR1 is defined.  This
patch checks it.  OK to install?

Thanks.
