fix: `SDKROOT` build setting, interpolated when under `CARTHAGE` to set `macosx`, otherwise set `iphoneos` — allowing Xcode·s GUI to show Mac Catalyst destinations. (#491)

Of minor note is the unfortunate reality that — as of commit «99f51f3» — `xcodebuild archive --showBuildSettings --skipUnavailableActions -project Sentry·xcodeproj -scheme Sentry` will no longer display the same `macosx`-`SDKROOT`–based build settings that `xcodebuild archive Sentry·xcodeproj` builds with (even when `-destination 'generic/platform=macOS'` is suffixed on at the end.)

More pressing note: `SUPPORTED_PLATFORMS` in service of ‘single target, multiple platform’ extrapolation has some restrictions — but, not especially burdensome.

And one unfortunate shortcoming of `SUPPORTED_PLATFORMS` future potential under Carthage gets denoted.
