Include VNDK snapshot modules only if the arch matches

If the target_arch for the snapshot module does not match with
the build variable TARGET_ARCH, hide the module from the make file.

Bug: 71787263
Test: Install VNDK snapshot v27
      lunch aosp_arm64_ab-userdebug; m vndk_v27_arm64
      - vndk libs must be installed
      m vndk_v27_arm
      - no vndk libs must be installed because target does not match
