Subject: travis: fix macOS 10.12 legacy build

brew update tries to update the java cask, which it tries to build from
source. this takes too long and leads to a timeout of the job. we can't
manually remove the java cask because of a bug in the too old brew cask
version and the old formula. we just remove the whole cask tap and call
it a day, since we don't need it anyway.
