Fix linking errors when using shared libraries.

We accomplish that by passing the module version as a string to the
constructors of LogOutputHelper and EclGenericOutputBlackoilModel
instead of calling moduleVersionName() in LogOutputHelper. That way
moduleVersionName is not needed by libopmsimulators anymore and
compilation works again for people requesting shared libraries via
CMake's BUILD_SHARED_LIBS variable.
