ARROW-3931: [C++] Make possible to build regardless of LANG

[sarutak]

At the time of building C++ libs, CompilerInfo.cmake checks the version of compiler to be used.
How to check is string matching of output of gcc -v or like clang -v.
When LANG is not related to English, build will fail because string match fails.
The following is the case of ja_JP.UTF-8 (Japanese).

  gcc バージョン 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) 

I fixed this issue by modifying CompilerInfo.cmake.

I took a shot at fixing this. If this doesn't work I'll fire up my Windows machine to work on it

[sarutak]

It seems to be fine. Thanks for fixing it!
