Unable to uninstall zip + portable package if the target exe file is in a subfolder

Brief description of your issue

For zip + portable packages, if the target executable file is in a subfolder of the zip archive, WinGet will always report the portable package has been modified and thus can't be uninstalled.

Steps to reproduce

Take https://github.com/microsoft/winget-pkgs/pull/92285 as an example, whose executable file is in the subfolder aria2-1.36.0-win-64bit-build1 (x64) or aria2-1.36.0-win-32bit-build1 (x86).

1. Run winget install -m .\a\aria2\aria2\1.36.0\, and WinGet works properly.
2. Run winget uninstall aria2.aria2__DefaultSource.

Expected behavior

WinGet should be able to uninstall the package.

Actual behavior

WinGet cannot uninstall the package and reports Unable to remove Portable package as it has been modified; to override this check use --force.

Start with the portable uninstall workflow at AppInstallerCLICore/Workflows/PortableFlow.cpp and reproduce the issue using the aria2 package and the listed winget install and uninstall commands. Trace why a target executable in a subfolder produces an empty expected symlink target; done means the package uninstalls successfully without --force and without reporting that the portable file was modified.
