PARQUET-437: Add googletest setup and ADD_PARQUET_TEST helper

I adapted this functionality from Apache Kudu (incubating). There are no real unit tests, yet, but you can now run `ctest` after building to run all tests that have been created with `ADD_PARQUET_TEST`.

Author: Wes McKinney <[email protected]>

Closes apache#19 from wesm/googletest-infra and squashes the following commits:

758328f [Wes McKinney] BLD: disable fixed OSX deployment target. Compile gtest with -fPIC
61cc5bb [Wes McKinney] Remove 'set -e' from setup_build_env.sh
6435970 [Wes McKinney] Fix setup_build_env.sh script
a54a219 [Wes McKinney] Add googletest to thirdparty and add ADD_PARQUET_TEST cmake helper and support scripts for using ctest after make
