Update using-dotnet-cli.md

The current directions for trying out your own build of coreclr are a little outdated. These edits update the directories and files names to match the locations where I was able to find the build output. I did not update the second half of the document.

I'd like to highlight two issues I encountered while trying this procedure.

A small one first: in a locally-built System.Private.CoreLib.dll, there is no git commit hash embedded. The nightly and preview builds do have the git hash. I don't know if this is intentional. I updated to the sample to remove the reference to the Git commit hash.

Secondly, when following this procedure, I get the following error:

  Determining projects to restore...
C:\test\test.csproj : error NU1102: Unable to find package Microsoft.WindowsDesktop.App.Runtime.win-x64 with version (= 5.0.0-dev)
C:\test\test.csproj : error NU1102:   - Found 25 version(s) in nuget [ Nearest version: 5.0.0-preview.1.20127.5 ]
C:\test\test.csproj : error NU1102:   - Found 0 version(s) in local CoreCLR
C:\test\test.csproj : error NU1102: Unable to find package Microsoft.AspNetCore.App.Runtime.win-x64 with version (= 5.0.0-dev)
C:\test\test.csproj : error NU1102:   - Found 28 version(s) in nuget [ Nearest version: 5.0.0-preview.1.20124.5 ]
C:\test\test.csproj : error NU1102:   - Found 0 version(s) in local CoreCLR

I was able to resolve this by editing a file in the SDK. In the Microsoft.NETCoreSdk.BundledVersions.props file, I commented out the KnownFrameworkReferences that mentioned in the error message. If this is not a known issue I should probably file a bug on the SDK. I did not covered this problem in my changes.

Lastly, I was going through this all to try out #40104. It looks great: according to PerfView, there are now zero foreground JIT compilations happening in hello world. The state of .NET single file packaging and AOT is much improved!

For the missing commit SHA, I'm guessing it's intentional:
https://github.com/dotnet/arcade/blob/3c56c9f23ce0d199baef41dd6831b42a2690ebc1/src/Microsoft.DotNet.Arcade.Sdk/tools/Version.BeforeCommonTargets.targets#L152

I made some updates. The second section of this file ## Update using runtime nuget package is still out of date and may not even be relevant anymore. Same for using-your-build.md.

Thanks for the changes.
