init tests: libhidl-gen-utils static

No longer installed on device, so we need to include
it as a static lib. This library was actually specified
as a dependency on vts_ibase_test in two places, so this
is the second CL doing the same thing but in another
project.

Fixes: 270497432
Test: readelf -d $ANDROID_BUILD_TOP/out/target/product/vsoc_x86_64/data/nativetest/vts_ibase_test/vts_ibase_test
  no longer shows libhidl-gen-utils
