Change linker config variable: VNDK_VER

With VNDK APEX, the path for VNDK libs has been changed
from /system/lib/vndk-VER to /apex/com.android.vndk.vVER/lib

Previously, VNDK_VER is replaced with prefix(e.g. "-29"). We could
still prepend prefix("v") to the vndk version, but this change uses a
raw vndk version as the value of VNKD_VER.
