Disable verify_uses_libraries check if dexpreopt is globally disabled.

Without dexpreopt the check is not necessary, and although it is good to
have, it is difficult to maintain on non-linux build platforms where
dexpreopt is generally disabled (the check may fail due to various
unrelated reasons, such as a failure to get manifest from an APK).
