ARROW-1193: [C++] Support pkg-config for arrow_python.so

I want it to create a Ruby library that integrates Python via Apache Arrow object in the same process.
[pycall](https://rubygems.org/gems/pycall) gem provides a feature to use Python objects in Ruby script in the same process. In this situation, we can change Apache Arrow data between Ruby and Python as Ruby/Python object instead of writing/reading Apache Arrow objects.

Closes #821 from kou/cpp-python-support-pkg-config and squashes the following commits:

12979fca [Kouhei Sutou] [C++] Don't link libpython
f473e667 [Kouhei Sutou] [C++] Support pkg-config for arrow_python.so
