eden: do not copy public_autocargo in internal builds

Summary:
The public_autocargo is for external builds, not internal ones as they contain
references to git repository, while the non-public_autocargo refers to path in
fbcode. In Sandcastle, git repositories can fail to be accessed due to lack fo
proxies, thus we shouldn't access them.
