Atlas配置bundle打包产物至assets目录

Atlas支持配置一个开关，将所有bundle打包到assets目录下。这样就不会导致bundle的apk产物被认为是动态链接库so。

atlas.tBuildConfig.keepInLibSoNames = null

附：Android获取手机cpu架构，支持的指令集

String[] abis = new String[]{};
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    abis = Build.SUPPORTED_ABIS;
} else {
    abis = new String[]{Build.CPU_ABI, Build.CPU_ABI2};
}
StringBuilder abiStr = new StringBuilder();
for (String abi : abis) {
    abiStr.append(abi);
    abiStr.append(', ');
}
Log.i("yezhou", "架构: " + abiStr.toString());
