fix OS X dsym file tags

The usage of the same dsym file tag in the app bundle and framework
bundle rules led to two separate rule paths.
One was creating a dylib
    cpp -> obj -> dylib -> dsym -> framework
the other created an app
    cpp -> obj -> app -> dsym -> app bundle
Using distinct file tags for application and dylib dsyms fixes this
conflict. We should detect and handle situations like this in a
subsequent commit.
