Dimitrios Liappis 589e880a9c Make cli arg parsing compliant with requirements.
Remove duplicate definition of GRADLE_OPT_TEST and rename arguments as
discussed in
https://github.com/elastic/x-plugins/pull/4137#discussion_r89660620

Default to `check` if no argument is passed, but exit with error in an
unsupported parameter is provided.

Also ensure the pipefail option is only set when the executing shell
is *really* bash as opposed to POSIX sh which doesn't support it.
