Update logic to add debug modules to art-runtime.

runtime_libart.mk no longer picks the debug APEX for userdebug builds,
so we can't do that here either.

This started to error out because the debug APEX is no longer
installable when it isn't picked by runtime_libart.mk.

Test: m nothing TARGET_BUILD_VARIANT=userdebug
Test: m nothing TARGET_BUILD_VARIANT=eng
