Install llndk.libraries.txt when VNDK is deprecated

llndk.libraries.txt is currently installed within VNDK APEX, while all
libraries are placed in system image, and list is still valid when VNDK
is deprecated. This change adds llndk.libraries.txt into the system
image, when VNDK is deprecated.

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