 Dynamically link all loaded packages in new object

 Summary:
 As a result of fixing #8935 we needed to open shared libraries
 with RTLD_LOCAL and so symbols from packages loaded earlier
 cannot be found anymore. We need to include in the link all
 packages loaded so far.

 This fixes #10058

 Test Plan: validate
