Disable to build ld.config.txt with previous vndk version

As generic ld.config.txt will be covered with linker config generator,
ld.config.txt with previous vndk build is no longer required. This
change removes this part so there will be no unnecessary build step for
multiple vndk version build. Also vndk snapshot will have vndkcore and
vndkprivate files with version number, update_and_install_ld_config.mk
has been updated temporary for vndk_lite build.
