Subject: Use llndk.libraries.txt from system if VNDK is deprecated

llndk.libraries.txt will be relocated into system when VNDK is
deprecated. This change sets a new location to load llndk.libraries.txt
when VNDK is deprecated.

Bug: 290160925
Test: aosp_cf build and boot succeeded with llndk.libraries.txt in the
system image
