shell32: shellpath tests failing greatly

[Rolf Kalbermatter]

The recently added tests for shellpath are failing almost completely on my
system as it is missing the according registry entries. Not sure how one is
supposed to get those registry entries properly. Maybe there is an install
script?
Although the current documentation talks about an utility wineinstall this
seems to have gone completely and I doubt it would take care of those settings.
