Only use framework-connectivity stubs for -t stubs

Do not use framework-connectivity stubs for
framework-connectivity-t-pre-jarjar, as that library can build against
the full framework-connectivity implementation including hidden symbols:
it already builds against framework-connectivity-pre-jarjar.

The stubs are only necessary to build framework-connectivity-t stubs, to
avoid circular dependencies between these and the framework-connectivity
implementation.

This change allows using hidden symbols of framework-connectivity in
framework-connectivity-t-pre-jarjar, but does not fully fix the problem
as framework-connectivity-t will use the framework-connectivity stubs
both to build its own stubs and to build its implementation library, due
to "libs" being used in both cases (and prioritized over
impl_only_libs). As a result, it is still not possible to build
framework-connectivity-t when it references hidden symbols of classes
that are also part of the stubs. Still, this is a first step and
organizes the build rules closer to what they should be.
