[md]### 【问题描述】

1. HAP包iBundleInstaller->StreamInstall进行安装报错
2. ```c++

auto sysAbilityMgr = OHOS::SystemAbilityManagerClient::GetInstance().GetSystemAbilityManager();
   if (sysAbilityMgr == nullptr) {
         PHLOGE("get system ability manager fail.");
         DeleteFiles();
         return APP_ERR_SYSTEM_ABNORMALLY;
   }

   auto remoteObject = sysAbilityMgr->GetSystemAbility(OHOS::BUNDLE_MGR_SERVICE_SYS_ABILITY_ID);
   auto iBundleMgr = iface_cast<AppExecFwk::IBundleMgr>(remoteObject);
   if (iBundleMgr == nullptr) {
         PHLOGE("can not get iBundleMgr");
         DeleteFiles();
         return APP_ERR_SYSTEM_ABNORMALLY;
   }

   auto iBundleInstaller = iBundleMgr->GetBundleInstaller();
   if ((iBundleInstaller == nullptr) || (iBundleInstaller->AsObject() == nullptr)) {
         PHLOGE("can not get iBundleInstaller");
         DeleteFiles();
         return APP_ERR_SYSTEM_ABNORMALLY;
   }

   sptr<AppInstallCallback> callback = new (std::nothrow) AppInstallCallback();
   if (callback == nullptr) {
         PHLOGE("AppInstallCallback failed");
         DeleteFiles();
         return APP_ERR_SYSTEM_ABNORMALLY;
   }

   AppExecFwk::InstallParam installParam;
   installParam.installFlag = AppExecFwk::InstallFlag::REPLACE_EXISTING;
   std::vector<std::string> realPaths = { hapPath };

   ErrCode ret = iBundleInstaller->StreamInstall(realPaths, installParam, callback);
   ret = callback->GetResultCode();
   std::string errorMessage = callback->GetResultMsg();
   PHLOGE("StreamInstall resultCode %{public}d resultMsg %{public}s.", ret, errorMessage.c_str());
```

4. 我尝试过修改hap包权限，修改bundle_permission_mgr.cpp中 `VerifyCallingPermissionForAll`直接返回ture
5. hap能通过 `iBundleInstaller->StreamInstall(realPaths, installParam, callback)`正常安装到设备中
