Relax apex package restriction for T+ jars

The ART AOT exemption only applies to Q/R/S, so module jars that have
min_sdk T+ do not need to follow the module package restriction, even if
they are part of a Q/R/S module (but not loaded on Q/R/S).

Relax the restriction to only apply to jars that have min_sdk before T.

(clean cherry-pick)
