BUILD: CI: move cygwin builds to Github Actions
builds on travis-ci fail because of
https://travis-ci.community/t/cygwin-issue-cygheap-base-mismatch-detected/5359
unfortunately, documentation does not help.
so, let us move builds to Github Actions.
also, remove deprecated "sudo" directive from .travis.yml
