`dotnet publish` creating wrong executable name

[sandyarmstrong]

Tested on OS X 10.12.5 with .NET Core 2.0.0-preview2-006497.

Steps to reproduce

1. mkdir PublishTest.WithDot && cd PublishTest.WithDot (must be a dotted name to exhibit bug)
2. dotnet new console
3. Add <RuntimeIdentifiers>win-x64;osx.10.11-x64</RuntimeIdentifiers> in the default PropertyGroup in the generated csproj.
4. dotnet build && dotnet publish -r osx.10.11-x64
5. ls bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot*

Expected Results

bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.deps.json
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.dll
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.pdb
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.runtimeconfig.json

Actual Results

bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.WithDot
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.deps.json
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.dll
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.pdb
bin/Debug/netcoreapp2.0/osx.10.11-x64/publish/PublishTest.WithDot.runtimeconfig.json

The incorrectly-named executable does not work until it is renamed:

$ cd bin/Debug/netcoreapp2.0/osx.10.11-x64/publish

$ chmod +x PublishTest.WithDot.WithDot

$ ./PublishTest.WithDot.WithDot
The managed DLL bound to this executable: 'PublishTest.WithDot.dll', did not match own name 'PublishTest.WithDot.WithDot.dll'.
A fatal error was encountered. This executable was not bound to load a managed DLL.

$ mv PublishTest.WithDot.WithDot PublishTest.WithDot

$ ./PublishTest.WithDot
Hello World!

This is a regression since the 1.0.4 SDK.

I believe this is a duplicate of dotnet/cli#6397, fixed in the latest builds by #1378.
