ARROW-2982: Ensure release verification script works with wget < 1.16, build ORC in C++ libraries

I also wrote a guide to setting up Ubuntu Linux (14.04 and higher) to be able to run from a cold start. I may have missed some stuff from a brand new install; others can keep updating. Eventually we should Dockerize for Ubuntu 14.04, 16.04, and 18.04: https://cwiki.apache.org/confluence/display/ARROW/How+to+Verify+Release+Candidates
