Mono/C#: Fix Android AAB export failing to load native libs

By default, when installing from Android App Bundles the native
libraries are not extracted. They are loaded directly from the APK.
See: https://stackoverflow.com/a/56551499

Passing only the file name to dlopen, without the location, makes it
search the native library in all locations, including inside the apk.
