For CI - simplify build matrix for Travis Mac build environment. Since our past assumptions of what is necessary and what is working may no longer valid now due to changes from Travis and from upgraded versions of the software we use, also due to the removal of the number of archs being included in our build, the build matrix setup is simplified without the past speed improvement and workaround scripts. We may modify our setup again depends on the need in the future CI builds. [skip appveyor] [ci only: OSX]
