dev-dotnet/dotnetcore-sdk-bin: able to install multiple .NET Core SDK major versions

The dotnetcore-sdk-bin package now uses slots for different major
versions. These can be installed parallel, the shared files between
these are provided by the new dotnetcore-sdk-bin-common package.

The non-slotted versions are removed to avoid confusion.

Fixes: https://github.com/gentoo/dotnet/issues/433
