Skip automatic on/off keepalives before U.

The API to start them was only added in U.

The actual failure here is not an error in calling the API, it's
the fact that the test is using CollectionUtils from the
framework jar instead of statically linked copy. This might be
a problem with jarjar rules. That said, given that these APIs
are module-lib, and were only added in U, it's probably OK to
test them only on U.
