Only copy native binaries on native-bridge configs

If native-bridge/ndk translation is supported for a config the build
system will know about 2 copies of binaries, one for each ABI. We only
want to actually install the 'Native' (non-translated) ABI into the
apex in these situations.

Test: lunch aosp_cf_x86_phone-userdebug
      m showcommands com.android.runtime.debug
      examine the command output to make sure only a single copy of
      dex2oat is being installed.
