Change all references to macOS

[dwijnand]

Change all references to macOS (MacOS X, MacOSX, OS X, OSX, macOSx, macosx, osx).

That leaves the TRAVIS_OS_NAME env var, which seems to only supports
the variant 'osx', as far as I can tell.

It also leaves the packageOsxDmg/package-osx-dmg task key, that is
both public binary API and public semantic API, as keys are global in
sbt's build state - so I just left it as is for now.

Hehe, there's a branch protection status check rule on scripted-osx, so this is going to be perma-pending on that, I predict.

For the record, scripted-macos passed (https://github.com/sbt/sbt-native-packager/pull/1301/checks?check_run_id=417762763)

The AppVeyor failure seems unrelated to this?

Thanks for your pull request 🤗

Where did you see this 😮 I haven't found anything in the project settings.

[muuki88]

Yeah. The appveyor build is broken since a few days / weeks. I haven't had the time yet to look into it.
