NuGet config not copied when running the workload command under sudo on Arm64

[ivdiazsa]

Describe the bug

Follow-up of https://github.com/dotnet/runtime/issues/72308. When one runs dotnet workload under sudo in an Arm64 machine, it will only work once, and then fail any subsequent times.

To Reproduce

Run sudo dotnet workload list on any macOS or Linux arm64 machine twice in a row. The second one will fail. Up to the latest nightly build as of August 8th, it still reproduced.

Exceptions (if any)

Segmentation Fault if using an official build, DirectoryNotFoundException if using a local build from this repo.

As discussed back here (https://github.com/dotnet/runtime/issues/72308#issuecomment-1200036996), the cause of this problem is that the NuGet config is attempted to be copied into the dotnet_sudo_home directory, but its full destination path is never created.

The code suggested in the comment referenced above in SudoEnvironmentDirectoryOverride.cs is a possible fix to this problem.

sudo home doesn't exist anymore with yesterday's release and the code has changed a lot. Please try again.
