Add shared library packages to app cache database using F-DroidPrivilegedExtension query

PackageManager filters some packages from getInstalledPackages if the calling uid is not root, shell or system or does not have install permissions granted. Additionally, the hidden MATCH_STATIC_SHARED_LIBRARIES flag must be set.
https://review.calyxos.org/c/CalyxOS/platform_packages_apps_F-DroidPrivilegedExtension/+/2305
We added an API call in F-DroidPrivilegedExtension given it has the necessary requirements to get the unfiltered results from getInstalledPackages. This allows shared library packages to be added to the app cache database which will allow F-Droid to update them
