Fix nxPackage not handling status deinstall

[gurrajatwal]

Pull Request (PR) description

nxPackage is not handling the case where a package has status deinstall. It considers a package to be installed if it has status deinstall. I made a temporary fix to address this issue and consider deinstall to be uninstalled.

More information on what deinstall means: https://manpages.ubuntu.com/manpages/noble/en/man1/dpkg.1.html deinstall: The package is selected for deinstallation (i.e. we want to remove all files, except configuration files)
