[mlpack] [mlpack/mlpack] Fixes #755 Log compatibility with std::fixed and std::setprecision (#832)

[Ryan Curtin]

Nice, thanks!  Can you add this test to `cli_test.cpp` and see if it works?

```
BOOST_AUTO_TEST_CASE(TestFormattedOutput)
{ 
  std::stringstream ss;
  PrefixedOutStream pss(ss, BASH_GREEN "[INFO ]" BASH_CLEAR);
  
  const double pi = std::acos(-1.0);
  pss << std::precision(10) << pi;
  
  BOOST_REQUIRE_EQUAL(ss.str(),
      BASH_GREEN "[INFO ]" BASH_CLEAR "3.141592654");
}
```

After building `mlpack_test` you can test with `mlpack_test -t CLITest/TestFormattedOutput`.
