Reenable LUCI notifications on the ART Buildbot AOSP builders.

The clean steps on the AOSP builders (aosp-builder-cc and
aosp-builder-cms) used to call "make clean", which sometimes failed
with this error:

  Failed to remove file "out/.module_paths":
  unlinkat out/.module_paths: directory not empty

As a result the LUCI notitications for these builders were disabled.

The clean steps are now using "rm -rf out" instead of "make clean",
which presubmably addressed the previous issue. Reenable the LUCI
notifications for aosp-builder-cc and aosp-builder-cms.
