Make protobuf.*.outputDir public again

Make protobuf outputDir public again for usage with installSourceBase
when creating/installing a separate proto-only library product. Make
outputDir readonly since it should not be set by the user. Changed
artifacts tag hpp to protobuf.hpp for better filtering.
