Update sdk_version check for jni_libs of updatable apps

With aosp/1640364, all variants of a cc_* module use min_sdk_version as
the version part of the clang triple. Therefore, checking
min_sdk_version of jni_libs should be sufficient to ensure that there is
no unintended access to symbols in newer Android versions
