Clean up unused art_module_* products.

The standard module_* products used by banchan work well to enable
building ART from source, using the logic in
build/make/core/android_soong_config_vars.mk where
ART_MODULE_BUILD_FROM_SOURCE is set to true when TARGET_BUILD_APPS has
an ART module in it.

#codehealth

Test: Edit build/make/core/android_soong_config_vars.mk to set
      BRANCH_DEFAULT_MODULE_BUILD_FROM_SOURCE false
      banchan com.android.art x86_64
      build/soong/soong_ui.bash --dumpvar-mode ART_MODULE_BUILD_FROM_SOURCE
  Check that the result is true and TARGET_PRODUCT is module_x86_64,
  which means that that product works fine to enable building ART from
  source.
