Self-contained app crashes when placed in a path with backslashes in Unix

[mateoatr]

Publishing a self-contained application in a path with a back slash in it causes the app to crash with Failed to create CoreCLR, HRESULT: 0x80004005.

A minimal repro:

dotnet new console -o foo
cd foo
dotnet publish -o a\\\\b -r linux-x64
cd a\\\\b
./foo

Update issue: this looks like a problem with the runtime when placed in a folder with backslashes
