Running into Windows path length limits for installer log files

Brief description of your issue

This is somewhat related to https://github.com/microsoft/winget-cli/issues/1808 but for installer log files. Because winget sets the log location to an already deep path, the log files that get created by the installer can more easily run into the 260 path length limit of Windows.

In the repro below, the installer attempts to create a log with the path of C:\Users\WDAGUtilityAccount\AppData\Local\Packages\Microsoft.DesktopAppInstaller_8wekyb3d8bbwe\LocalState\DiagOutputDir\WinGet-Microsoft.dotnet.6.1.322.12413-2022-03-22-14-16-07.487_013_Microsoft.NET.Sdk.Android.Manifest_6.0.100.31.0.101_preview.9.16_x64.msi.log which is over the path length limit.

Steps to reproduce

1. git clone https://github.com/microsoft/winget-pkgs.git
2. cd winget-pkgs
3. git checkout 5e9640f
4. .\Tools\SandboxTest.ps1 manifests\m\Microsoft\DotNet\6.1.322.12413

Expected behavior

.NET SDK should be successfully installed in Windows Sandbox environment.

Actual behavior

Install fails.

No source file or test is named. Start by running Tools/SandboxTest.ps1 with manifests/m/Microsoft/DotNet/6.1.322.12413 and trace how the installer log path is selected. Done means the reported .NET SDK installation succeeds without exceeding Windows' path-length limit.
