remove unnecessary tests
cc: @nitins17  Thanks for the PR. Are these blocking the current MacStadium builds? If not, lets keep it as is because our internal macOS Arm64 builds will be using the scripts in https://github.com/tensorflow/tensorflow/tree/master/ci/official. Those do not install any build dependencies from requirements.txt AFAIK so we should be good there as well.  @nitins17 These are blocking at the moment, this PR just brings the files up to parity with the workaround that is currently in place  Okay, thanks for clarifying, LGTM! 
Removing the tests that caused issues due to duplicated dependencies. Also these tests have been deemed redundant.
