[dotnet] Updated COPR to 1.1

[Nemanja Milošević]

Hey guys,

one more update after the today's meeting, I've updated my builds to .NET
Core 1.1.

I've decided to keep it in a separate COPR, as people maybe using the old
builds still.

Here is the link:

https://copr.fedorainfracloud.org/coprs/nmilosev/dotnet1.1/

Version information:

Version:            1.0.0-preview2-1-003177
Commit SHA-1 hash:  a2df9c2576

Of course, please remember that this is just an easier way of installing
binary dotnet on F24/F25/Rawhide while we are creating the proper package.

Hope you are all well!

Kind regards,
Nemanja
