C++17 drops support for `std::random_shuffle`, breaking C++17 compilers
that run to compile text2image.cpp. std::shuffle is valid on C++11
through C++17, so use std::shuffle instead.
Due to the use `std::random_shuffle`, `text2image --render_ngrams`
would not give consistent results for different compilers or platforms.
With the current change, the same random number generator is used for
all platforms and initialized to the same seed, so training output
should be consistent.
This allows using new features of C++17 conditionally.
Simplify also the code which checks and sets the C++ version.

AC_CHECK_FILE does not work in cross builds. Such builds aborted.
Replace it by AC_CHECK_HEADERS. This fixes cross builds.
To enable TensorFlow in cross builds, more work is needed.
