windows-build/tar: Move to running under ubuntu

* On windows specifying only filenames to exclusions causes things like
  `tar: .editorconfig: Cannot stat: No such file or directory`

  But putting `EDMarketConnector/` prefix on such means they don't work.

* Testing with 'git bash' GNU tar 1.34:

  `tar -c -v -z -f edmc-test.tar.gz --exclude=.editorconfig --exclude=.git\* EDMarketConnector`

  works, with empty output from:

  `tar tfvz edmc-test.tar.gz | grep editorconfig`
