build: drop the properties that switch off the assembly attributes of the SDK

The library project switched on the generation of assembly attributes, which
Directory.Build.props had switched off, and then switched off the nine
attributes that AssemblyInfo.fs provided, so that the SDK generated the
InternalsVisibleTo attribute alone.

FAKE writes the assembly information as MSBuild properties now, and the SDK
generates all attributes. The InternalsVisibleTo item works as it is, and the
project needs none of the properties.
