libnativeloader understands uses-native-library tag
Previously, libnativeloader provided all the partner-provided public
shared libraries to apps unconditionally. Starting from Android S, apps
targeting S (or higher) get only the libs that are explicited listed
as dependencies using the <uses-native-library> tag in the app manifest.
The libs not listed there are not available to the app even if they are
registered as public libraries.
The changed behavior affects new (S+) apps. Existing apps are not
affected; they still get all the libraries.
The implementation is rather straightforward. The library accepts a new
parameter soname_list from the framework, which is actually from the
<uses-native-library> tags of the app manifest. The list is used to
filter the partner-provided libraries when the target sdk is > 30.
