travis: config rewrite to have osx working again

Do not attempt to run python2 tests on osx.

Homebrew updating was taking a long time, causing timeouts.

Reduced the number of homebrew formulas to cut down install time.
Some of the removed ones are already provided in the osx image.

osx_image updated because only the newer ones work without
travis's homebrew addon flag 'update: true'
https://changelog.travis-ci.com/xcode-11-3-1-xcode-11-2-1-xcode-11-1-and-xcode11-images-updated-142286

Config updated with the help of live validator:
https://config.travis-ci.com/explore

Added sudo flag "-H" to "sudo pip*" as pip suggests.

Trying to make use of cached of $HOME/perl_modules.
