Install jni symlinks in Soong
The installation of the symlink
(<partition>/app/MyApp/lib/<arch>/libfoo.so) and its target
(/system/lib64/libfoo.so) are now done int Soong.
I gave up the idea of always embedding jni libs to apps, due to a
hard-to-fix regression in storage usage. Specifically, consider this
case.
app --(jni_lib)--> libfoo
--(jni_lib)--> libbar
libfoo --(shared_lib)--> libbar
Ideally, with the embedding idea, both libfoo and libbar should be
embedded into the app and there should be no libfoo or libbar outside of
the apk, unless there's no dependency to any of them from outside of the
apk.
However, the previous implementation installed libbar to /system/lib64,
leading two copies of the lib; one in /system/lib64, the other in the
apk.
This was happening because libbar was also considered as a transitive
dep of libfoo, and therefore a dependency to its installation path is
added to the apk. The problem here is that the app doesn't know that
libfoo depends on libbar. We in theory can write a very delicate
dependency traverse routine which filters libbar out of the transitive
deps, but that looked too complicated.
