libsubzero is available to vendor modules

The static library is used by vendor modules libGLESv2_swiftshader and
libGLESv1_CM_swiftshader. Therefore libsubzero also needs to be marked
as vendor module, otherwise, build fails when built with
BOARD_VNDK_VERSION.

Test: choosecombo 1 aosp_arm usedebug
Test: BOARD_VNDK_VERSION=current m -j
