test: check for GNU parallel with --version options

The lastest versions of GNU parallel no longer make mention of GNU
within their help output. This causes the test script to mistakenly use
the moreutils parallel execution. In order to fix this, while
maintaining compatibility with previous versions of GNU parallel,
--version should be used.
